From: Kalle Valo Date: Wed, 20 Apr 2016 16:46:01 +0000 (+0300) Subject: ath10k: switch testmode to use ath10k_core_fetch_firmware_api_n() X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=9dfe240b4d684f17efa861e92e45dc949b0049ed;p=openwrt%2Fstaging%2Fblogic.git ath10k: switch testmode to use ath10k_core_fetch_firmware_api_n() Now that all firmware-N.bin related are within struct ath10k_fw_file we can switch to use ath10k_core_fetch_firmware_api_n() and delete almost identical ath10k_tm_fetch_utf_firmware_api_2().
