[PATCH v3 0/2] mailbox: ti-msgmgr: Fixes for polled rx and trailing bytes

[Beleswar Padhi <b-padhi@ti.com>]

This series fixes two issues in ti_msgmgr_send_data(), found while
refactoring the ti-msgmgr mbox client (TI-SCI).

Patch 1 fixes a duplicate message transmission in polled rx mode.
Patch 2 stops reading past the end of the message buffer when the
message length is not a multiple of 4. This is a preparatory patch for
when the mbox client can send data which is not a multiple of 4.

This series is independent and can be applied directly.

v3: Changelog:
1. Add Fixes: tag in [PATCH v3 2/2].
