Subject: [PATCH 1/3] ps3: vuart: fix error path locking
Date: Wed, 12 Dec 2007 00:00:01 -0800 [thread overview]
Message-ID: <20071213003028.676998182@mvista.com> (raw)
Message-ID: <20071213003023.117964080@mvista.com> (raw)
This stray down would cause a permanent sleep which doesn't seem correct.
The other uses of this semaphore appear fairly mutex like it's even initialized
with init_MUTEX() .. So here a patch for removing this one down().
