Subject: ath79/mikrotik: use standard caldata functions
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=1e24af5638f1c7263c10157afd7b25b9bf601c0c;p=oweals%2Fopenwrt.git

ath79/mikrotik: use standard caldata functions

With the implementation of a sysfs interface to access WLAN data, this
target no longer needs a special wrapper to extract caldata.
