Subject: [patch] hotplug/shpchp_hpc: add parenthesis in SLOT_REG_RSVDZ_MASK
Date: Wed, 26 May 2010 10:46:39 +0000 [thread overview]
Message-ID: <20100526104639.GA16631@bicker> (raw)
The SLOT_REG_RSVDZ_MASK macro is normally used like this:
slot_reg &= ~SLOT_REG_RSVDZ_MASK;
The ~ operator has higher precedence than the | operator from inside the
macro, so it needs parenthesis.
