udev 182: response timeout for request_firmware in module_probe path

[Ming Lei]

Hi Kay,

I found that udev 182 doesn't response for the request_firmware in
module_probe path until 30sec later after the 'ADD' event of firmware
device, but no such problem in udev175, sounds like a regression of udev?

I find there was a related discussion in [1], so CC guys who discussed before.

Just grep under kernel root dir, there are about 360 request_firmware callers,
and looks most of them are called in .probe path.
