Subject: [PATCH 21/30] scsi: aic94xx: aic94xx_dump: Remove code that has been unused for at least 13 years
Date: Wed,  3 Mar 2021 14:46:22 +0000	[thread overview]
Message-ID: <20210303144631.3175331-22-lee.jones@linaro.org> (raw)
In-Reply-To: <20210303144631.3175331-1-lee.jones@linaro.org>

Fixes the following W=1 kernel build warning(s):

 drivers/scsi/aic94xx/aic94xx_dump.c:731: warning: expecting prototype for asd_dump_ddb_site(). Prototype was for asd_dump_target_ddb() instead
 drivers/scsi/aic94xx/aic94xx_dump.c:875: warning: expecting prototype for ads_dump_seq_state(). Prototype was for asd_dump_seq_state() instead
