Subject: ath9k: Fix PS wrappers in ath9k_set_coverage_class
From: Mohammed Shafi Shajakhan <[email protected]>
commit 8b2a3827bb12430d932cd479b22d906baf08c212 upstream.
this callback is called during suspend/resume and also via iw command.
it configures parameters like sifs, slottime, acktimeout in
ath9k_hw_init_global_settings where few REG_READ, REG_RMW are also done
and hence the need for PS wrappers
