Commit Message

Brent Pappas Jan. 13, 2024, 5:27 p.m. UTC 
  Annotates ieee80211_set_beacon_cntdwn() with a __must_hold() annotation to
make it clear that ieee80211_set_beacon_cntdwn() is only intended to be
called when the caller has a lock on the argument "link."

Changelog:
v1 -> v2: Include linux/compiler_types.h with angle brackets instead of
          quotes.
