* wireless: Use octal not symbolic permissionsJoe Perches2018-03-27
| | | | | | | | | | | | | | Prefer the direct use of octal for permissions. Done with checkpatch -f --types=SYMBOLIC_PERMS --fix-inplace and some typing. Miscellanea: o Whitespace neatening around these conversions. Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
* rt2500usb: constify usb_device_idArvind Yadav2017-08-10
| | | | | | | | | usb_device_id are not supposed to change at runtime. All functions working with usb_device_id provided by <linux/usb.h> work with const usb_device_id. So mark the non-const structs as const. Signed-off-by: Arvind Yadav <arvind.yadav.cs@gmail.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

* rt2x00: change function pointers for register accessorsArnd Bergmann2017-05-24
| | | | | | | | | | This prepares the driver for changing all the 'read' register accessors to return the value instead of passing it by reference. Since a lot of them are used in callbacks, this takes care of the callbacks first, adding a couple of helpers that will be removed again one at a time.

* rt2500usb: don't mark register accesses as inlineArnd Bergmann2017-02-15
| | | | | | | | | | | | | | | | | When CONFIG_KASAN is set, we get a rather large stack here: drivers/net/wireless/ralink/rt2x00/rt2500usb.c: In function 'rt2500usb_set_device_state': drivers/net/wireless/ralink/rt2x00/rt2500usb.c:1074:1: error: the frame size of 3032 bytes is larger than 100 bytes [-Werror=frame-larger-than=] If we don't force those functions to be inline, the compiler can figure this out better itself and not inline the functions when doing so would be harmful, reducing the stack size to a merge 256 bytes. Note that there is another problem that manifests in this driver, as a result of the typecheck() macro causing even larger stack frames.

* rt2x00: add support for mac addr from device treeMathias Kresin2016-11-08
| | | | | | | | | | | | | | On some devices the EEPROMs of Ralink Wi-Fi chips have a default Ralink MAC address set (RT3062F: 00:0C:43:30:62:00, RT3060F: 00:0C:43:30:60:00). Using multiple of these devices in the same network can cause nasty issues. Allow to override the MAC in the EEPROM with (a known good) one set in the device tree to bypass the issue.

* rt2x00: fix monitor mode regressionEli Cooper2016-01-25
| | | | | | | | | | | | | | Since commit df1404650ccb ("mac80211: remove support for IFF_PROMISC") monitor mode for rt2x00 has been made effectively useless because the hardware filter is configured to drop packets whose intended recipient is not the device, regardless of the presence of monitor mode interfaces. This patch fixes this regression by adding explicit monitor mode support, and by configuring the hardware filter accordingly.

* rt2x00: type bug in _rt2500usb_register_read()Dan Carpenter2015-11-30
| | | | | | | | | | | | | | | | | | | | | This code causes a static checker bug. drivers/net/wireless/ralink/rt2x00/rt2500usb.c:232 _rt2500usb_register_read() warn: passing casted pointer 'value' to 'rt2500usb_register_read()' 32 vs 16. If the low 16 bits were initialized to zero then this code would only be a problem on big endian systems. But in this case this is case the low 16 bits are never initialized. This is called from a function which is created using a macro: RT2X00DEBUGFS_OPS(csr, "0x%.8x\n", u32); We end up copying uninitialized data to the user which is bogus and an information leak.
