[0/2] Fixes NULL pointer access in spi-mt65xx.c

Message

Hi,

This series contains two patches for spi-mt65xx.c, both focusing on its
interrupt handler mtk_spi_interrupt().

The first patch is to fix a NULL pointer access in the interrupt
handler, which is first found on a MT8186 Chromebook device when the
system tries to establish host communication with its embedded
controller.

The second one is a decorative clean-up when I'm working on the first
patch, which simply renames a variable to better follow the rest of the
code.
I put this after the first fix because I think that will make
maintainers and users slightly easier to only backport the fix if
needed.

Looking forward to any feedback, thank you.

Regards,
Fei

Sorry, I found I messed things up in the last rebase and this doesn't compile.
I'll send a v2 soon so please disregard this series.
