The `val' variable in ath5k_eeprom_read_turbo_modes() is used uninitialized. gcc 4.4.1 with -fno-inline-functions-called-once reports it: eeprom.c: In function 'ath5k_eeprom_read_turbo_modes': eeprom.c:441: warning: 'val' may be used uninitialized in this function Comparing the code to the Atheros HAL, it's clear that the split between ath5k_eeprom_read_modes() and ath5k_eeprom_read_turbo_modes() was incorrect. The Atheros HAL reads both turbo and non-turbo data from EEPROM in one function. Some turbo mode parameters are derived from the same EEPROM values as non-turbo parameters, just from different bits. Merge ath5k_eeprom_read_turbo_modes() into ath5k_eeprom_read_modes() to fix the warning. The actual values and offsets have been cross-checked against Atheros HAL. Signed-off-by:

As Pavel Roskin noted, the check for mac version as copied from legacy_hal made no sense. This replaces it with the equivalent and makes up a suitable #define for the mac version legacy_hal checked. Signed-off-by:

The ICT IRQ table is a set of __le32 values, not u32 values, so when reading it we need to take into account that it has to be converted to CPU endianness. This was causing a lot of trouble on my powerpc box where various things would simply not work for no apparent reason with 5xxx cards, but worked with 4965 -- which doesn't use the ICT table.

Since patch "rt2x00: bss_info_changed() callback is allowed to sleep" the variable delayed wasn't used anymore. This means it can be removed along with the call to schedule_work which depended on that variable. Signed-off-by:

-Fix a few nasty typos (b43_phy_* operations instead of b43_radio_*) in the channel tune routines. -Fix some typos & spec errors found by MMIO tracing. -Optimize b43_phy_write & b43_phy_mask/set/maskset to use only the minimal number of MMIO accesses. (Write is possible using a single 32-bit MMIO write, while set/mask/maskset can be done in 3 16-bit MMIOs). -Set the default channel back to 1, as the bug forcing us to use channel 7 is now fixed. With this, the device comes up, scans, associates, transmits, receives, monitors and injects on all channels - in other words, it's fully functional. Sensitivity and TX power are still sub-optimal, due to the lack of calibration (that's next on my list). Signed-off-by:

The Qdiv roundup routine is essentially a fixed-point division algorithm, using only integer math. However, the version in the specs had a major error that has been recently fixed (a missing quotient++). Replace Qdiv roundup with a rewritten, simplified version. Signed-off-by:

This function currently does initialization + enable the btcoex support. Split it into two logical functions which does the above operations separately. Btcoex initialization is done during attach time and enabling this feature is done in start(). Also, add code to disable btcoex support in stop(). Signed-off-by:

The maze of if() statements in configure_filter is confusing. Reorganizing it as a switch statement makes it more apparent what is going on and reveals several suspicious settings. This has no functional changes, though it does remove some redundant flags that are set earlier. Also now that we can sleep, protect sc->filter_flags with the sc lock. Signed-off-by:
