Subject: mwifiex: wake system up when receives a wake irq
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ef7e0714742541dcce75b646b64f7a376b7d4368;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

mwifiex: wake system up when receives a wake irq

Currrently we are disabling this wake irq after receiving it. If this
happens before we finish suspend and the pm event check is disabled,
the system will continue suspending, and this irq would not work again.

We may need to abort system suspend to avoid that.
