From 117a1542c0bc9bcce0c5b9bc63ff54dc967acdf5 Mon Sep 17 00:00:00 2001 From: Xiaoke Wang Date: Thu, 7 Apr 2022 17:33:49 +0800 Subject: [PATCH] clk: pxa: add a check for the return value of kzalloc() kzalloc() is a memory allocation function which can return NULL when some internal memory errors happen. So it is better to check it to prevent potential wrong memory access.
