[PATCH] lib: Use kzalloc() instead of kmalloc() with flag GFP_ZERO.

From: Yi Wang
Date: Wed Feb 12 2020 - 04:54:29 EST


From: Huang Zijiang <huang.zijiang@xxxxxxxxxx>

Use kzalloc instead of manually setting kmalloc
with flag GFP_ZERO since kzalloc sets allocated memory
to zero.

Change in v2:
add indation
