Subject: [PATCH v4 1/8] ath10k: clean up error handling in ath10k_core_probe_fw()
Date: Wed, 3 Dec 2014 10:09:31 +0200	[thread overview]
Message-ID: <20141203080931.31187.15394.stgit@potku.adurom.net> (raw)
In-Reply-To: <20141203080803.31187.85059.stgit@potku.adurom.net>

Use the error handling style preferred in ath10k. Makes it easier to add
ath10k_init_firmware_features() function in the next patch.
