Summary
Input: iforce - wake up after clearing IFORCE_XMIT_RUNNING flag
Details

In the Linux kernel, the following vulnerability has been resolved:

Input: iforce - wake up after clearing IFORCEXMITRUNNING flag

syzbot is reporting hung task at __inputunregisterdevice() [1], for iforce_close() waiting at waiteventinterruptible() with dev->mutex held is blocking inputdisconnectdevice() from __inputunregisterdevice().

It seems that the cause is simply that commit c2b27ef672992a20 ("Input: iforce - wait for command completion when closing the device") forgot to call wakeup() after clearbit().

Fix this problem by introducing a helper that calls clearbit() followed by wakeup_all().
