[PATCH] ASoC: q6dsp: q6apm: replace kzalloc() with kcalloc() in q6apm_map_memory_regions()

[Ethan Carter Edwards <ethan@xxxxxxxxxxxxxxxxx>]

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.
