Subject: ath9k: Fix key cache slot selection for splitmic
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=ea6121328885640c137b0a8830f67ca6c386a24a;p=linux-beck.git

ath9k: Fix key cache slot selection for splitmic

ath_reserve_key_cache_slot() was obviously supposed to return an index
to a free slot, not reserved one. This could have caused problems with
hardware revisions that use splitmic.
