From c254b52b58b50a8599fefefd8793a64249b15044 Mon Sep 17 00:00:00 2001 From: Bart Van Assche Date: Thu, 8 Aug 2019 20:01:29 -0700 Subject: [PATCH] scsi: qla2xxx: Declare the fourth ql_dump_buffer() argument const This patch makes it clear to humans and also to the compiler that ql_dump_buffer() does not modify the memory the @buf argument points at.
