Subject: [PATCH 03/10] qla2xxx: Replace two macros with an inline function
Date: Thu, 4 Jun 2015 15:53:59 -0700 [thread overview]
Message-ID: <5570D707.2010009@sandisk.com> (raw)
In-Reply-To: <5570D656.9050704@sandisk.com>
Replace the QLA82XX_ADDR_IN_RANGE() and QLA8044_ADDR_IN_RANGE() macros
with the inline function addr_in_range(). This avoids that the compiler
reports the following warning when building with W=1: comparison of
unsigned expression >= 0 is always true.
