      ath9k_hw: fix parsing of HT40 5 GHz CTLs · 90487974
      Luis R. Rodriguez authored
      
      
      The 5 GHz CTL indexes were not being read for all hardware
      devices due to the masking out through the CTL_MODE_M mask
      being one bit too short. Without this the calibrated regulatory
      maximum values were not being picked up when devices operate
      on 5 GHz in HT40 mode. The final output power used for Atheros
      devices is the minimum between the calibrated CTL values and
      what CRDA provides.

      ath9k_hw: Fix EEPROM uncompress block reading on AR9003 · 803288e6
      Luis R. Rodriguez authored
      
      
      The EEPROM is compressed on AR9003, upon decompression
      the wrong upper limit was being used for the block which
      prevented the 5 GHz CTL indexes from being used, which are
      stored towards the end of the EEPROM block. This fix allows
      the actual intended regulatory limits to be used on AR9003
      hardware.

      netlink: Make NETLINK_USERSOCK work again. · b963ea89
      David S. Miller authored
      
      
      Once we started enforcing the a nl_table[] entry exist for
      a protocol, NETLINK_USERSOCK stopped working.  Add a dummy
      table entry so that it works again.

      irda: Correctly clean up self->ias_obj on irda_bind() failure. · 628e300c
      David S. Miller authored
      
      
      If irda_open_tsap() fails, the irda_bind() code tries to destroy
      the ->ias_obj object by hand, but does so wrongly.
      
      In particular, it fails to a) release the hashbin attached to the
      object and b) reset the self->ias_obj pointer to NULL.
      
      Fix both problems by using irias_delete_object() and explicitly
      setting self->ias_obj to NULL, just as irda_release() does.
