| * ALSA: hda - Add support for Lenovo S10-3tJerone Young2010-08-23

| * ALSA: hda - Fix stream and channel-ids codec-bus wideTakashi Iwai2010-08-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The new sticky PCM parameter introduced the delayed clean-ups of stream- and channel-id tags. In the current implementation, this check (adding dirty flag) and actual clean-ups are done only for the codec chip. However, with HD-audio architecture, multiple codecs can be on a single bus, and the controller assign stream- and channel-ids in the bus-wide. In this patch, the stream-id and channel-id are checked over all codecs connected to the corresponding bus. Together with it, the mutex is moved to struct hda_bus, as this becomes also bus-wide.

| * ALSA: hda - Fix conflict of sticky PCM parameter in HDMI codecsTakashi Iwai2010-08-20
| | | | | | | | | | | | | | | | | | | | | | Intel and Nvidia HDMI codec drivers have own implementations of sticky PCM parameters. Now HD-audio core part already has it, thus both setups conflict. The fix is simply remove the part in patch_intelhdmi.c and patch_nvhdmi.c and simply call snd_hda_codec_setup_stream() as usual.

* | ALSA: emu10k1 - delay the PCM interrupts (add pcm_irq_delay parameter)Jaroslav Kysela2010-08-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With some hardware combinations, the PCM interrupts are acknowledged before the period boundary from the emu10k1 chip. The midlevel PCM code gets confused and the playback stream is interrupted. It seems that the interrupt processing shift by 2 samples is enough to fix this issue. This default value does not harm other, non-affected hardware.

| | * | ACPI / ACPICA: Fix reference counting problems with GPE handlersRafael J. Wysocki2010-08-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a handler is installed for a GPE associated with an AML method and such that it cannot wake up the system from sleep states, the GPE remains enabled after the handler has been installed, although it should be disabled in that case to avoid spurious execution of the handler. Fix this issue by making acpi_install_gpe_handler() disable GPEs that were previously associated with AML methods and cannot wake up the system from sleep states. Analogously, make acpi_remove_gpe_handler() enable the GPEs that are associated with AML methods after their handlers have been removed and cannot wake up the system from sleep states. In addition to that, fix a code ordering issue in acpi_remove_gpe_handler() that renders the locking ineffective (ACPI_MTX_EVENTS is released temporarily in the middle of the routine to wait for the completion of events already in progress). For this purpose introduce acpi_raw_disable_gpe() and acpi_raw_enable_gpe() to be called with acpi_gbl_gpe_lock held and rework acpi_disable_gpe() and acpi_enable_gpe(), respectively, to use them. Also rework acpi_gpe_can_wake() to use acpi_raw_disable_gpe() instead of calling acpi_disable_gpe() after releasing the lock to avoid the possible theoretical race with acpi_install_gpe_handler().

But for one PCI device(0000:00:00.0) under the PCI root bridge, the corresponding address will be constructed as zero.In such case maybe the ACPI device without _ADR object will be misdetected and then be used to create the relationship between PCI device and ACPI device. https://bugzilla.kernel.org/show_bug.cgi?id=16422 Signed-off-by: Zhao Yakui <yakui.zhao@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>

There is a zero element on the end of the m25p_ids[] array and if we hit the end of the loop then plat_id points to that. This would lead to a NULL pointer dereference later on in the function.

These functions all check retlen inconsistently and it generates a warning in Smatch (http://smatch.sf.net). If retlen were ever NULL it would cause an oops and the code has been this way since 2006 so someone would have complained. Also I looked at other places that implemented the mtd read and write functions and they dereference retlen without checking. I removed the checks.
