You could split it up further. For example, you could introduce
the include file first. Also, please run checkpatch --strict on
your patches. I don't care about commenting the mutex, but there
should be no double empty lines. Also, while you are at it,
it would be great if you can add another patch to fix the

WARNING: Symbolic permissions 'S_IWUSR | S_IRUGO' are not preferred. Consider using octal permissions '0644'.

warnings.

Anyway, I wondered what changed... oh, I see. You didn't rename
nct6775.c. I didn't suggest that. The new file name was fine.
I only asked you to change the Kconfig symbols, not the file names.
It is ok and actually desirable to change the file names.
The platform driver module can and should still be named nct6775;
that can be handled in the Makefile with something like

nct6775-objs := nct6775-platform.o
obj-$(CONFIG_SENSORS_NCT6775)  += nct6775.o
