Subject: iwlwifi: mvm: wake up d0i3_exit_waitq when aborting d0i3
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=caf1578aefe7ebbc22376737e91ffa29ac14a33f;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

iwlwifi: mvm: wake up d0i3_exit_waitq when aborting d0i3

When aborting d0i3 due to taken refs, other threads might
already wait on d0i3_exit_waitq for IWL_MVM_STATUS_IN_D0I3
to get cleared (it's somewhat likely, as synchronize_rcu()
might take a while), so make sure to wake them up.
