Subject: [PATCH 15/20] 53c700: Open-code status_byte(u8) calls
Date: Tue, 13 Apr 2021 10:07:09 -0700	[thread overview]
Message-ID: <20210413170714.2119-16-bvanassche@acm.org> (raw)
In-Reply-To: <20210413170714.2119-1-bvanassche@acm.org>

The 53c700 driver is one of the two drivers that passes an u8 argument
to status_byte() instead of an s32 argument. Open-code status_byte in
preparation of changing SCSI status values into a structure.
