Subject: wifi: rtw89: chan: simplify link handling related to ROC
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=2fed8de4eb98764e559189eb3bac9d3f2954cb95;p=thirdparty%2Fkernel%2Flinux.git

wifi: rtw89: chan: simplify link handling related to ROC

The original channel is swapped out for the target channel during ROC.
And, all vifs/links accessing the original channel will be marked with
off-channel. So, it doesn't seem necessary for chan.c to determine which
link instance it is.
