Subject: [PATCH v2] ath9k: Fix PS wrappers in ath9k_set_coverage_class
Date: Wed, 24 Aug 2011 21:38:07 +0530	[thread overview]
Message-ID: <1314202087-18296-1-git-send-email-mohammed@qca.qualcomm.com> (raw)

From: Mohammed Shafi Shajakhan <mohammed@qca.qualcomm.com>

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
