[PATCH 0/2] dell-smm-hwmon: Add XPS 13 9360 to supported devices list

[Haochen Tong]

This patch adds Dell XPS 13 9360 to supported devices list in
dell-smm-hwmon.

I have tested this on one such device and verified that the fan speed is
correctly reported, and can be controlled through pwm1{,_enable}.

Hello! In patch 2/2 you are using DMI_EXACT_MATCH. I think it does not
make sense to use substring match in one case and exact match in another
case for one specific machine. I would suggest to use one type of match
for both cases.
