Subject: [PATCH 2/4] dpt_i2o: make adpt_i2o_to_scsi() a void function
Date: Fri, 15 Nov 2019 09:05:53 +0100	[thread overview]
Message-ID: <20191115080555.146710-3-hare@suse.de> (raw)
In-Reply-To: <20191115080555.146710-1-hare@suse.de>

The return value is never used anywhere, and returning it
risks a use-after-free crash.

Signed-off-by: Hannes Reinecke <hare@suse.de>
