Subject: ath10k: clean up error handling in ath10k_core_probe_fw()
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=c6ce492d03e89e1f1a30cbdab777e9367baeae34;p=openwrt%2Fstaging%2Fblogic.git

ath10k: clean up error handling in ath10k_core_probe_fw()

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