The HECC_CANMIM is set in the xmit path and cleared in the interrupt. Since this is done with a read, modify, write action the register might end up with some more MIM enabled then intended, since it is not protected. That doesn't matter at all, since the tx interrupt disables the mailbox with HECC_CANME (while holding a spinlock). So lets just always keep MIM set. While at it, since the mailbox direction never changes, don't set it every time a message is send, ti_hecc_reset() already sets them to tx.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
