      NFC: llcp: Use list_for_each_entry in nfc_llcp_find_local() · 29e27dd8
      Axel Lin authored 
      nfc_llcp_find_local() does not modify any list entry while iterating the list.
So use list_for_each_entry instead of list_for_each_entry_safe.

      NFC: Remove redundant test for dev->n_targets in nfc_find_target · 365a721a
      Axel Lin authored 
      Without this test, it returns NULL if dev->n_targets is 0 anyway.

      brcmfmac: Make probe function __init · c2d23c70
      Jean Delvare authored 
      One of the benefits of platform_driver_probe() is that you can make
the probe function __init.

      ath9k: Convert uses of __constant_<foo> to <foo> · 1b5c8d60
      Joe Perches authored 
      The use of __constant_<foo> has been unnecessary for quite awhile now.

Make these uses consistent with the rest of the kernel.

      ath5k: add missing dma_map_error call · b499abdc

      Trivial patch to address this trace. Now calls dma_mapping_error and
return -ENOSPC if a problem found.

      ath9k_hw: set ANI firstep as absolute values instead of relative · 9301ca90
      Felix Fietkau authored 
      On older chips, the INI value differ in similar ways as cycpwr_thr1, so
convert it to absolute values as well.

Since the ANI algorithm is different here compared to the old
implementation (fewer steps, controlled at a different point in time),
it makes sense to use values similar to what would be applied for newer
chips, just without relying on INI defaults.

      ath9k_hw: set ANI cycpwr_thr1 as absolute values instead of relative · 28327fd0
      Felix Fietkau authored 
      The table was copied from the ANI implementation of AR9300. It assumes
that the INI values contain a baseline value that is usable as reference
from which to increase/decrease based on the noise immunity value.

On older chips, the differences are bigger and especially AR5008/AR9001
are configured to much more sensitive values than what is useful.

Improve ANI behavior by reverting to the absolute values used in the
previous implementation (expressed as a simple formula instead of the
old table).

      ath9k_hw: remove ANI function restrictions for AP mode · afdc05f0
      Felix Fietkau authored 
      The primary purpose of this piece of code was to selectively disable
OFDM weak signal detection. The checks for this are elsewhere, and an
earlier commit relaxed the restrictions for older chips, which are more
sensitive to interference.

      wireless: Kconfig: add missing dependency for airo_cs · a0b2a8f4
      Arnd Bergmann authored 
      commit 4c59ff22 "wireless: Kconfig: add missing dependency" added a number
of 'depends on CFG80211' statements, but missed the AIRO_CS driver that
also causes the airo.c file to be built. This adds the (hopefully) last
such missing statement
