Subject: wl1251: remove wl1251_ops
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=0e71bb084adc4986b9a4be3581897f0ee703cbd5;p=openwrt%2Fstaging%2Fblogic.git

wl1251: remove wl1251_ops

Now wl1271 is splitted to separate files, no need to use wl1251_ops anymore.
So remove struct wl1251_chip and wl1251_ops.c.
