X-Git-Tag: microblaze-v5.10~660^2~111^2~13^2~97
X-Git-Url: http://git.monstr.eu/?a=commitdiff_plain;h=635cb0105e01f4c90e69b3cf8e2c1569479e4bf7;p=linux-2.6-microblaze.git

mt76: mt7615: disable hw/sched scan ops for non-offload firmware

Avoid having to attempt hw scan and fall back to software for every scan
on devices/firmware without hw scan support
