Subject: [PATCH 0/2] firmware loader: avoid blocking suspend by !uevent requests

Hi,

Recently, Takashi reported that requests with FW_ACTION_NOHOTPLUG may block
shutdown and fixed that by killing pending requests before shutdown. But
these requests still may block suspend, so the 2 patches is introduced to
fix the problem during suspend.

The 2nd patch depends on Takashi Iwai's patch of "firmware: Avoid deadlock of
usermodehelper lock at shutdown".

Thanks,
