From: Kalle Valo Date: Wed, 3 Dec 2014 08:10:08 +0000 (+0200) Subject: ath10k: add ATH10K_FW_IE_WMI_OP_VERSION X-Git-Tag: firefly_0821_release~176^2~2371^2~10^2~180^2~25 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=202e86e60646d6987e3a3e63871453401e72d451;p=firefly-linux-kernel-4.4.55.git ath10k: add ATH10K_FW_IE_WMI_OP_VERSION Instead of using feature flags, add new 32 bit variable for managing different WMI versions. This makes it firmware interface tests a bit less convoluted, especially when we add one more interface.
