X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=4f82eecf73019c27537f65c160e90385e159afd8;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

ath9k: Fix queue handling in flush()

When draining of the TX queues fails, a
full HW reset is done. ath_reset() makes sure
that the queues in mac80211 are restarted,
so there is no need to wake them up again.
