SubjectRe: thermal/drivers/hisi: Remove bogus const from function return type

Interesting.

I intentionally asked Daniel to include the modifier because sparse
pointed this to me:

This patch adds this issue to hisi driver (sparse)

drivers/thermal/hisi_thermal.c:398:24: warning: incorrect type in assignment (different modifiers)
drivers/thermal/hisi_thermal.c:398:24: expected int ( *platform_probe )( ... )
drivers/thermal/hisi_thermal.c:398:24: got void const *

which makes sense to me to be const, given that it is receiving the return
of a function which returns a const void *.
nclude/linux/of_device.h:extern const void *of_device_get_match_data(const struct device *dev);

Cheers,
