Subject: [PATCH] bfa: turn bfa_mem_{kva,dma}_setup into inline functions
Date: Wed, 16 Nov 2016 16:14:27 +0100	[thread overview]
Message-ID: <20161116151445.3208739-1-arnd@arndb.de> (raw)

These two macros cause lots of warnings with gcc-7:

drivers/scsi/bfa/bfa_svc.c: In function 'bfa_fcxp_meminfo':
drivers/scsi/bfa/bfa_svc.c:521:103: error: '*' in boolean context, suggest '&&' instead [-Werror=int-in-bool-context]

Using inline functions makes them much more readable and avoids
the warnings.
