Henrique de Moraes Holschuh fc589a3ce5 ACPI: thinkpad-acpi: allow for syscall restart in sysfs handlers
Map an mutex_lock_interruptible() error return into ERESTARTSYS, as the
only possible error from mutex_lock_interruptible is EINTR, and that will
only happen if signal_pending() causes the mutex lock attempt to abort.

This still allows signals to be delivered ASAP, which is much nicer than
just doing mutex_lock, and still shadows userspace from EINTR when
SA_RESTART is active.

Problem reported by Peter Jordan.
