* p54usb: fix leaks at failure path in p54u_probe()Alexey Khoroshilov2014-03-141-0/+4
| | | | | | | | | | | If p54u_load_firmware() fails, p54u_probe() does not deallocate already allocated resources. The patch adds proper failure handling.

* p54: clamp properly instead of just truncatingDan Carpenter2014-01-131-1/+1
| | | | | | | | | The call to clamp_t() first truncates the variable signed 8 bit and as a result, the actual clamp is a no-op. Fixes: 0d78156eef1d ('p54: improve site survey') Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

* | p54: use ether_addr_equal_64bitsJulia Lawall2014-01-031-1/+1
|/ | | | | | | | | | | | | | | | Ether_addr_equal_64bits is more efficient than ether_addr_equal, and can be used when each argument is an array within a structure that contains at least two bytes of data beyond the array. The structures involved are: ieee80211_hdr defined in include/linux/ieee80211.h and p54_common defined in drivers/net/wireless/p54/p54.h This was done using Coccinelle (http://coccinelle.lip6.fr/).

John W. Linville says: ==================== Regarding the Bluetooth bits, Gustavo says: "The big work here is from Marcel and Johan. They did a lot of work in the L2CAP, HCI and MGMT layers. The most important ones are the addition of a new MGMT command to enable/disable LE advertisement and the introduction of the HCI user channel to allow applications to get directly and exclusive access to Bluetooth devices." As to the ath10k bits, Kalle says: "Bartosz dropped support for qca98xx hw1.0 hardware from ath10k, it's just too much to support it. Michal added support for the new firmware interface. Marek fixed WEP in AP and IBSS mode. Rest of the changes are minor fixes or cleanups." And also: "Major changes are: * throughput improvements including aligning the RX frames correctly and optimising HTT layer (Michal) * remove qca98xx hw1.0 support (Bartosz) * add support for firmware version 999.999.0.636 (Michal) * firmware htt statistics support (Kalle) * fix WEP in AP and IBSS mode (Marek) * fix a mutex unlock balance in debugfs file (Shafi) And of course there's a lot of smaller fixes and cleanup." For the wl12xx bits, Luca says: "Here are some patches intended for 3.13. Eliad is upstreaming a bunch of patches that have been pending in the internal tree. Mostly bugfixes and other small improvements." Along with that... Arend and friends bring us a batch of brcmfmac updates, Larry Finger offers some rtlwifi refactoring, and Sujith sends the usual batch of ath9k updates. As usual, there are a number of other small updates from a variety of players as well. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | My commit "p54: parse output power table" introduced the following compiler warnings for powerpc-allmodconfig eeprom.c: In function 'p54_get_maxpower': eeprom.c:291 warning: comparison of distinct pointer types lacks a cast eeporm.c:292 warning: comparison of distinct pointer types lacks a cast eeprom.c:293 warning: comparison of distinct pointer types lacks a cast eeprom.c:294 warning: comparison of distinct pointer types lacks a cast This patch fixes those by using max_t(u16 which forces a type cast.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For the upcoming tpc changes, the driver needs to provide sensible max output values for each supported channel. And while the eeprom always had a output_limit table, which defines the upper limit for each frequency and modulation, it was never really useful for anything... until now. Note: For anyone wondering about what your card is calibrated for: check "iw list". * 2412 MHz [1] (18.0 dBm) * 2437 MHz [6] (19.0 dBm) [...] * 5180 MHz [36] (18.0 dBm) * 5260 MHz [52] (17.0 dBm) (radar detection) * 5680 MHz [136] (19.0 dBm) (radar detection) (for a Dell Wireless 1450 USB Adapter) Signed-off-by: Christian Lamparter <chunkeey@googlemail.com> Signed-off-by: John W.

* | p54pci: convert driver to use asynchronous firmware loadingLarry Finger2012-08-062-26/+63
|/ | | | | | | | | | | | | | Drivers that load firmware from their probe routine have problems with the latest versions of udev as they get timeouts while waiting for user space to start. The problem is fixed by using request_firmware_nowait() and delaying the start of mac80211 until the firmware is loaded. To prevent the possibility of the driver being unloaded while the firmware loading callback is still active, a completion queue entry is used.
