Priority P4 18

In the Linux kernel, the following vulnerability has been resolved:

clk: clocking-wizard: Fix Oops in clk_wzrd_register_divider()

Smatch detected this potential error pointer dereference
clk_wzrd_register_divider(). If devm_clk_hw_register() fails then
it sets "hw" to an error pointer and then dereferences it on the
next line. Return the error directly instead.
