[PATCH] thermal/debugfs: replace kzalloc() with kcalloc() in thermal_debug_tz_add()

[Ethan Carter Edwards]

We are trying to get rid of all multiplications from allocation
functions to prevent integer overflows[1]. Here the multiplication is
obviously safe, but using kcalloc() is more appropriate and improves
readability. This patch has no effect on runtime behavior.
