Subject: [PATCH] scsi: ufs: Use PTR_ERR_OR_ZERO to replace the open coded version
Date: Tue, 27 Nov 2018 15:50:25 +0800	[thread overview]
Message-ID: <20181127075025.16018-1-wen.yang99@zte.com.cn> (raw)

PTR_ERR_OR_ZERO has implemented the same function, so use inlined function
instead of open coded equivalent.
