Subject: wil6210: support regular scan on P2P_DEVICE interface
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=321a000bfadd5535089a198b42d714a8bf8469b7;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

wil6210: support regular scan on P2P_DEVICE interface

P2P search can only run on the social channel (channel 2).
When issuing a scan request on the P2P_DEVICE interface,
driver ignored the channels argument and always performed a P2P
search.
Fix this by checking the channels argument, if it is
not specified (meaning full scan) or if a non-social channel
was specified, perform a regular scan and not a P2P search.
