Petersen" , linux-scsi@vger.kernel.org Cc: Jack Wang Subject: [PATCH v2 10/10] scsi: pm8001: Remove PM8001_READ_VPD Date: Tue, 12 Sep 2023 08:27:45 +0900 Message-ID: <20230911232745.325149-11-dlemoal@kernel.org> X-Mailer: git-send-email 2.41.0 In-Reply-To: <20230911232745.325149-1-dlemoal@kernel.org> References: <20230911232745.325149-1-dlemoal@kernel.org> MIME-Version: 1.0 Precedence: bulk List-ID: X-Mailing-List: linux-scsi@vger.kernel.org Remove the macro PM8001_READ_VPD used to define if a controller WWN should be retrieved from the device. Instead, define the better named boolean module parameter "read_wwn" to control this. The code to set a fixed address for a phy device address when read_wwn is set to false is simplified and fixed to avoid sparse warnings.
