Subject: [PATCH] Fix namespace conflict between w9968cf.c on MIPS
Date: Sun, 10 Dec 2006 19:41:44 +0000	[thread overview]
Message-ID: <20061210194144.GA423@linux-mips.org> (raw)

Both use __SC.  Since __* is sort of private namespace I've choosen to
fix this in the driver.  For consistency I decieded to also change
__UNSC to UNSC.
