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().
