Subject: rfkill: honour EPO state when resuming a rfkill controller
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=176707997bc3da2c4e32715c35cfebba0334ed68;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

rfkill: honour EPO state when resuming a rfkill controller

rfkill_resume() would always restore the rfkill controller state to its
pre-suspend state.

Now that we know when we are under EPO, kick the rfkill controller to
SOFT_BLOCKED state instead of to its pre-suspend state when it is resumed
while EPO mode is active.
