Subject: [PATCH v5 04/49] scsi: nsp_cs: Change the return type of two functions into 'void'
Date: Fri, 18 Feb 2022 11:50:32 -0800	[thread overview]
Message-ID: <20220218195117.25689-5-bvanassche@acm.org> (raw)
In-Reply-To: <20220218195117.25689-1-bvanassche@acm.org>

nsp_reselected() and nsphw_init() always return TRUE. Change the return type
of these functions into 'void'.
