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)

[-- Attachment #1: ps3-vuart-locking-fix.patch --]
[-- Type: text/plain, Size: 770 bytes --]

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().
