Subject: Re: [PATCH 2/2] ELAN U132 Host Controller Driver: convert
scheduler_lock to mutex
A corrected version of the patch, the first one contained context
removed by the first patch of this serie
--
The ELAN U132 Host Controller Driver uses the semaphore scheduler_lock
as mutex. Use the mutex API instead of the (binary) semaphore.
