From b9468ad8ff65e6dcfeb69cab15deecafdb883643 Mon Sep 17 00:00:00 2001 From: Marc Kleine-Budde Date: Fri, 1 Mar 2019 16:27:59 +0100 Subject: [PATCH] can: flexcan: flexcan_mailbox_read() make use of flexcan_write64() to mark the mailbox as read In the previous patch the function flexcan_write64() was introduced. This patch replaces the open coded variant in flexcan_mailbox_read() that marks a mailbox as read, by a single call to flexcan_write64().
