Subject: wl1271: Fix channel changing code
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ddb01a5b368270f3cc86b606ba6f7ee8795a8a99;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

wl1271: Fix channel changing code

channel change, breaking connectivity, and b) not update the channel number
at all for ad-hoc, breaking adhoc.
