Subject: ar71xx: add an extra check on board_name for ath10k firmware patchs
X-Git-Tag: reboot~4959
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=a28d07abbe42379845fc230ed49af6e5f895d73b;p=openwrt%2Fopenwrt.git

ar71xx: add an extra check on board_name for ath10k firmware patchs

It moves firmware patch code behind an extra check on board_name.
Otherwise it will calculate firmware checksum for unaffected boards.
It also reduce boottime by a md5 calculation and removes error message
on boot if firmware not found.
