Subject: clk: Fix incorrect return type in clk.c
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=5fda6858a49c2d8706adcc05f083b64af172d3eb;p=linux-beck.git

clk: Fix incorrect return type in clk.c

Return type of function clk_propagate_rate_change is a pointer.
But 0 was being returned. Change it to NULL.
Silences the following warning:
drivers/clk/clk.c:977:24: warning: Using plain integer as NULL pointer
