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().
 |
