Subject: [PATCH 02/40] scsi: aic7xxx: aic79xx_core: Remove a bunch of unused variables
Date: Tue, 21 Jul 2020 17:41:10 +0100 [thread overview]
Message-ID: <20200721164148.2617584-3-lee.jones@linaro.org> (raw)
In-Reply-To: <20200721164148.2617584-1-lee.jones@linaro.org>
Question: Can 'ahd_inb(ahd, LQISTAT2);' also be safely removed?
Fixes the following W=1 kernel build warning(s):
drivers/scsi/aic7xxx/aic79xx_core.c: In function ‘ahd_dump_sglist’:
drivers/scsi/aic7xxx/aic79xx_core.c:1738:14: warning: variable ‘len’ set but not used [-Wunused-but-set-variable]
