      ieee80211: remove redundant leading zeroes · 03512ceb
      由 Sara Sharon 提交于 
      The defines of IEEE80211_HE_OPERATION_VHT_OPER_INFO and
IEEE80211_HE_OPERATION_MULTI_BSSID_AP have leading zeroes
that makes the number look like it is bigger than 32 bit.
This is misleading, remove it.

non-data packets that need powersave buffering, so add a
hardware flag to allow this.

      mac80211: remove pointless 'params' NULL checks · 6f527287
      由 Johannes Berg 提交于 
      These checks aren't necessary, cfg80211 never passes NULL.
Some static checkers complain about the missing checks on
the next line, but really the NULL checks are unnecessary.

      Not all SFPs implement the registers containing sensor limits and
alarms. Luckily, there is a bit indicating if they are implemented or
not. Add checking for this bit, when deciding if the hwmon attributes

      net: sched: action_ife: take reference to meta module · 84cb8eb2
      由 Vlad Buslov 提交于 
      Recent refactoring of add_metainfo() caused use_all_metadata() to add
metainfo to ife action metalist without taking reference to module. This
causes warning in module_put called from ife action cleanup function.

Implement add_metainfo_and_get_ops() function that returns with reference
to module taken if metainfo was added successfully, and call it from
use_all_metadata(), instead of calling __add_metainfo() directly.

Example warning:

      net: phy: mscc: factorize code for LEDs mode · 11bfdabb
      由 Quentin Schulz 提交于 
      LEDs modes are set the same way, except they are offset by 4 times the
index of the LED.

Let's factorize all the code so that it's easier to add support for the
4 LEDs of the VSC8584 PHY.
