mac80211: Add ieee80211_hw pointer to get_expected_throughput

2016-08-05T12:23:25+00:00

The variable is added to allow the driver an easy access to
it's own hw->priv when the op is invoked.

This fixes a crash in wlcore because it was relying on a
station pointer that wasn't initialized yet. It's the wrong
way to fix the crash, but it solves the problem for now and
it does make sense to have the hw pointer here.

tree-wide: replace config_enabled() with IS_ENABLED()

2016-08-04T12:50:07+00:00

The use of config_enabled() against config options is ambiguous.  In
practical terms, config_enabled() is equivalent to IS_BUILTIN(), but the
author might have used it for the meaning of IS_ENABLED().  Using
IS_ENABLED(), IS_BUILTIN(), IS_MODULE() etc.  makes the intention
clearer.

This commit replaces config_enabled() with IS_ENABLED() where possible.
This commit is only touching bool config options.

I noticed two cases where config_enabled() is used against a tristate
option:

 - config_enabled(CONFIG_HWMON)
  [ drivers/net/wireless/ath/ath10k/thermal.c ]

 - config_enabled(CONFIG_BACKLIGHT_CLASS_DEVICE)
  [ drivers/gpu/drm/gma500/opregion.c ]

I did not touch them because they should be converted to IS_BUILTIN()
in order to keep the logic, but I was not sure it was the authors'
intention.

rtlwifi: don't add include path for rtl8188ee

2016-07-19T18:17:41+00:00

For rtl8188ee, we pass -Idrivers/net/wireless/rtlwifi/ to gcc,
however that directy no longer exists, so evidently this option
is no longer required here and can be removed to avoid a warning
when building with 'make W=1' or 'gcc -Wmissing-include-dirs'

wlcore: spi: add wl18xx support

2016-07-19T18:16:04+00:00

Add support for using with both wl12xx and wl18xx.

- all wilink family needs special init command for entering wspi mode.
  extra clock cycles should be sent after the spi init command while the
  cs pin is high.
- Use inverted chip select for sending a dummy 4 bytes command that
  completes the init stage.

brcmsmac: Initialize power in brcms_c_stf_ss_algo_channel_get()

2016-07-19T18:14:20+00:00

wlc_phy_txpower_get_current() does a logical OR of power->flags, which
presumes that power.flags was initiliazed earlier by the caller,
unfortunately, this is not the case, so make sure we zero out the struct
tx_power before calling into wlc_phy_txpower_get_current().
