      rt2x00: Remove intf->bssid field. · 773d1b98
      Gertjan van Wingerde 提交于
      The bssid field in struct rt2x00_intf is only written to once, and is
      never read from.
      
      Remove this field, as it appears to not be needed.

      rt2x00: allow txstatus_fifo w/o txstatus_tasklet · 5235189c
      Johannes Stezenbach 提交于
      When DRIVER_REQUIRE_TXSTATUS_FIFO is set, intialize the
      txstatus_fifo, but initialize rt2x00dev->txstatus_tasklet
      only when both DRIVER_REQUIRE_TXSTATUS_FIFO and
      rt2x00dev->ops->lib->txstatus_tasklet are set.
      
      This allows the txstatus_fifo to be used by rt2800usb which
      does not use txstatus_tasklet.

      carl9170: fix usb pm suspend->resume woes · 97e2c402
      Christian Lamparter 提交于
      This patch revamps some common code-paths which are
      shared between (re-)initialization and suspend/resume
      subroutines. It also adds some helpful comments
      about quirks and associated difficulties.
      
      It's quite big, but it should fix #25382:
      <https://bugzilla.kernel.org/show_bug.cgi?id=25382>
      
      And hopefully the code is robust enough to deal with
      all possible suspend/resume scenarios without requiring
      the user to do any sort of manual and possibly
      dangerous work.

      carl9170: reduce channel change delay · 3b386510
      Christian Lamparter 提交于
      By removing two "safety" msleeps (and an echo nop), the
      channel change delay is effectively halved. Previously,
      the delay could be as long as 260 ms and the device
      could not go off-channel without risking to miss the
      next DTIM beacon [interval ~307 ms].

      ath5k: fix cycle counter inconsistent locking · bb007554
      Bob Copeland 提交于
      ath5k_reset is called from process context and takes the cc_lock
      with plain spin_lock(), but cc_lock can also be taken from tasklets
      in softirq context.  Thus we need to at least use spin_lock_bh.
      
      This fixes the following lockdep warning:

      For the AR9002, the spur frequency read from the EEPROM is mangled
      before being compared against AR_NO_SPUR.  This results in the driver
      trying to set up the spur mitigation for bogus spurs, rather than
      cleanly breaking out.
