Subject: [PATCH v4 2/8] ath10k: create ath10k_core_init_features()
Date: Wed, 3 Dec 2014 10:09:59 +0200	[thread overview]
Message-ID: <20141203080958.31187.62552.stgit@potku.adurom.net> (raw)
In-Reply-To: <20141203080803.31187.85059.stgit@potku.adurom.net>

It's easier to manage firmware version differences when we configure them in
one place. Rename ath10k_core_init_max_sta_count() to
ath10k_core_init_firmware_features() and start moving most of the firmware
version ("features") handling to that function.
