This will lead to backtraces like: (scatterwalk_start) from [<c01312f4>] (scatterwalk_map_and_copy+0x2c/0xa8) (scatterwalk_map_and_copy) from [<c013a5a0>] (crypto_ccm_decrypt+0x7c/0x25c) (crypto_ccm_decrypt) from [<c032886c>] (ieee80211_aes_ccm_decrypt+0x160/0x170) (ieee80211_aes_ccm_decrypt) from [<c031c628>] (ieee80211_crypto_ccmp_decrypt+0x1ac/0x238) (ieee80211_crypto_ccmp_decrypt) from [<c032ef28>] (ieee80211_rx_handlers+0x870/0x1d24) (ieee80211_rx_handlers) from [<c0330c7c>] (ieee80211_prepare_and_rx_handle+0x8a0/0x91c) (ieee80211_prepare_and_rx_handle) from [<c0331260>] (ieee80211_rx+0x568/0x730) (ieee80211_rx) from [<c01d3054>] (__carl9170_rx+0x94c/0xa20) (__carl9170_rx) from [<c01d3324>] (carl9170_rx_stream+0x1fc/0x320) (carl9170_rx_stream) from [<c01cbccc>] (carl9170_usb_tasklet+0x80/0xc8) (carl9170_usb_tasklet) from [<c00199dc>] (tasklet_hi_action+0x88/0xcc) (tasklet_hi_action) from [<c00193c8>] (__do_softirq+0xcc/0x200) (__do_softirq) from [<c0019734>] (irq_exit+0x80/0xe0) (irq_exit) from [<c0009c10>] (handle_IRQ+0x64/0x80) (handle_IRQ) from [<c000c3a0>] (__irq_svc+0x40/0x4c) (__irq_svc) from [<c0009d44>] (arch_cpu_idle+0x2c/0x34) Such packets can appear for example when using the carl9170 wireless driver because hardware sometimes generates garbage when the internal FIFO overruns. This patch adds an additional length check.

The expression, (32-logmask) is comprised between 0 and 31 included. It may be equal to 31. In such a case the left shift will produce a signed integer overflow. According to the C99 Standard, this is an undefined behavior. A simple fix is to replace the signed int 1 with the unsigned int 1U.

Here we just let DELL_WMI_MIC_MUTE_LED be chained to ALC269_FIXUP_HEADSET_MODE, then the machine will have these quirks ALC293_FIXUP_DELL1_MIC_NO_PRESENCE--> ALC269_FIXUP_HEADSET_MODE-->ALC255_FIXUP_DELL_WMI_MIC_MUTE_LED.

So if DELL_WMI_MIC_MUTE_LED still chain ALC255_FIXUP_DELL1_MIC_NO_PRESENCE, the machine can't use this quirk. To change this situation, let the DELL_WMI_MIC_MUTE_LED to be a standalone quirk, and let other quirks chain it. After this change, this quirk can be chained to any existing quirks, and as a result, it is possible that this quirk is applied to a non-Dell machine or a Dell machine without mic mute led on it, but it is still safe since alc_fixup_dell_wmi() will return an error in these situations. And remove the quirk for machine with subsystem id 0x6010 and 0x601f, these two machines will fall back to the quirk ALC255_FIXUP_DELL1_MIC_NO_PRESENCE-->ALC255_FIXUP_HEADSET_MODE--> ALC255_FIXUP_DELL_WMI_MIC_MUTE_LED through pin_fixup_tbl[].

The other is a fix for non-DT machine driver matching following some of the componentization work which is much more focused. Both have had a while to cook in -next.

The SMALL_POP bit should fix this, but its definition is incorrect: according to the sgtl5000 manual it is bit 0 of CHIP_REF_CTRL register, not bit 1. Fix the definition accordingly and enable the bit as intended per the code comment.

Most of FE/BE state changes are protected by mutex, so that they won't race, but there are still some actions that are uncovered. For example, suppose to switch a BE while a FE's stream is running. This would call soc_dpcm_runtime_update(), which sets FE's runtime_update flag, then sets up and starts BEs, and clears FE's runtime_update flag again. When a device emits XRUN during this operation, the PCM core triggers snd_pcm_stop(XRUN). Since the trigger action is an atomic ops, this isn't blocked by the mutex, thus it kicks off DPCM's trigger action. It eventually updates and clears FE's runtime_update flag while soc_dpcm_runtime_update() is running concurrently, and it results in confusion. Usually, for avoiding such a race, we take a lock. There is a PCM stream lock for that purpose. However, as already mentioned, the trigger action is atomic, and we can't take the lock for the whole soc_dpcm_runtime_update() or other operations that include the lengthy jobs like hw_params or prepare. This patch provides an alternative solution. This adds a way to defer the conflicting trigger callback to be executed at the end of FE/BE state changes. For doing it, two things are introduced: - Each runtime_update state change of FEs is protected via PCM stream lock. - The FE's trigger callback checks the runtime_update flag. If it's not set, the trigger action is executed there. If set, mark the pending trigger action and returns immediately. - At the exit of runtime_update state change, it checks whether the pending trigger is present. If yes, it executes the trigger action at this point.

When matching a component by name for CODEC DAIs the code previous to the patch compared the name in the DAI link table with component->name. For CPU DAIs the code compared to dev_name(component->dev). The newly introduced function ended up using the later as well. For most components dev_name(component->dev) and component->name are the same. The main notable exception are I2C devices where the driver name and the device name are concatenated to form the component name. By using dev_name(component->dev) instead of component->name the patch broke the matching of I2C CODECs by name. This patch restores the original behavior by using component->name instead of dev_name(component->dev). This will be safe even for CPU DAIs since for CPU DAIs both are the same.

On those machines there are ACPI device objects for some I2C devices that can wake up the system from sleep states, but that is done via a platform-specific mechanism and the ACPI objects don't contain any wakeup-related information. When we started to use ACPI power management with those devices (which happened during the 3.13 cycle), their configuration confused the ACPI PM layer that returned error codes from suspend callbacks for them causing system suspend to fail. However, the ACPI PM layer can safely ignore the wakeup setting from a device driver if the ACPI object corresponding to the device in question doesn't contain wakeup information in which case the driver itself is responsible for setting up the device for system wakeup" * tag 'pm+acpi-3.18-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: ACPI / PM: Ignore wakeup setting if the ACPI companion can't wake up

Namely, they technically are wakeup-capable, but the wakeup is handled via a platform-specific out-of-band mechanism and the ACPI PM layer has no information on the wakeup capability. As a result, device_may_wakeup(dev) called from acpi_dev_suspend_late() returns 'true' for those devices, but the wakeup.flags.valid flag is unset for the corresponding ACPI device objects, so acpi_device_wakeup() reproducibly fails for them causing acpi_dev_suspend_late() to return an error code. The entire system suspend is then aborted and the machines in question cannot suspend at all. Address the problem by ignoring the device_may_wakeup(dev) return value in acpi_dev_suspend_late() if the ACPI companion of the device being handled has wakeup.flags.valid unset (in which case it is clear that the wakeup is supposed to be handled by other means). This fixes a regression introduced by commit a76e9bd89ae7 (i2c: attach/detach I2C client device to the ACPI power domain) as the affected systems could suspend and resume successfully before that commit.

Previously we used "unsigned long" to hold the bridge window address. But this is a bus address, so we should use dma_addr_t instead. Use dma_addr_t to hold the bridge window base and limit. The question of whether the CPU can actually *address* the window is separate and depends on what the physical address space of the CPU is and whether the host bridge does any address translation.

But it's better to apply them to all devices with a link because if the subordinate bus has not been allocated yet, we won't apply settings to the device. Use pcie_cap_has_lnkctl() to determine whether the device has a Link Control register instead of looking at dev->subordinate.
