Subject: [PATCH] ath9k_hw: fix 5 GHz frequency selection on AR934x/AR955x with 25 MHz refclock
Date: Sat, 14 Jul 2012 01:26:54 +0200 [thread overview]
Message-ID: <1342222014-27980-1-git-send-email-nbd@openwrt.org> (raw)
The old code was an accidental copy&paste of the 2.4 GHz version,
which doesn't work.
