Subject: input-linux: Reset il->fd handler before closing it
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=33d72145d783457973e29aed703b84f820763f47;p=qmiga%2Fqemu.git

input-linux: Reset il->fd handler before closing it

If object-del input-linux object on-the-fly, instance finalize will
close evdev fd without resetting it. However the main thread is still
trying to lock_acquire/lock_release during ppoll, which leads to a very
high CPU utilization.
