Subject: [PATCH v2 2/3] ath6kl: refactor wmi scan command
Date: Thu, 19 Jul 2012 16:00:48 +0300	[thread overview]
Message-ID: <20120719130048.22047.69322.stgit@x201> (raw)
In-Reply-To: <20120719125937.22047.91375.stgit@x201>

ATH6KL_FW_CAPABILITY_STA_P2PDEV_DUPLEX was checked in cfg80211.c which is
a bit awkward when adding more callsites to the scan functions. Refactor
the code to wmi.c so that it's transparent to the callers.

Even though the patch looks scary there are no functional changes. I
just had to move ath6kl_wmi_startscan_cmd() before
ath6kl_wmi_beginscan_cmd() which confuses patch.
