ath9k: Fix PS wrappers in ath9k_set_coverage_class
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 Cc: stable@kernel.org Signed-off-by: Mohammed Shafi Shajakhan <mohammed@qca.qualcomm.com> Signed-off-by: John W.
