Subject: [PATCH] mvsas: fix command_active typo
Date: Wed, 16 Nov 2016 16:08:34 +0100	[thread overview]
Message-ID: <20161116150855.3083872-1-arnd@arndb.de> (raw)

gcc-7 notices that the condition in mvs_94xx_command_active looks
suspicious:

drivers/scsi/mvsas/mv_94xx.c: In function 'mvs_94xx_command_active':
drivers/scsi/mvsas/mv_94xx.c:671:15: error: '<<' in boolean context, did you mean '<' ? [-Werror=int-in-bool-context]

This was introduced when the mv_printk() statement got added,
and leads to the condition being ignored. This is probably harmless.

Changing '&&' to '&' makes the code look reasonable, as we check the
command bit before setting and printing it.

Fixes: a4632aae8b66 ("[SCSI] mvsas: Add new macros and functions")
