From 6340760d0671e92b15ff92b7eda41bbdd9702437 Mon Sep 17 00:00:00 2001

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().
