Subject: [patch] staging: bcm: clean up a type issue in ConfigureEndPointTypesThroughEEPROM()
Date: Thu, 09 Jan 2014 05:44:29 +0000	[thread overview]
Message-ID: <20140109054429.GA13954@elgon.mountain> (raw)

We only ever set the highest 4 bytes of ulReg.  This would cause a
problem on big endian systems.  The type should be u32 instead of
unsigned long.
