Subject: cfg80211: invert P2P-Device vs. netdev check ordering
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6e3ab5543bed9dffb7d1a6404c3782284a432a70;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

cfg80211: invert P2P-Device vs. netdev check ordering

In cfg80211_can_use_iftype_chan(), check for P2P Device
first, and then for netdevs. This doesn't really change
anything but makes the code a bit easier to read since
it may not be obvious for everyone at first that a P2P
device has no netdev.
