Subject[PATCH 4.19 66/92] clk: clk-atlas6: fix return value check in atlas6_clk_init()
Date
From: Xu Wang <vulab@iscas.ac.cn>

[ Upstream commit 12b90b40854a8461a02ef19f6f4474cc88d64b66 ]

In case of error, the function clk_register() returns ERR_PTR()
and never returns NULL. The NULL test in the return value check
should be replaced with IS_ERR().
