[PATCH 3/8] clk: composite: return ERR_PTR on registration failure

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

From: Ahmad Fatoum <a.fatoum@barebox.org>

clk_register_composite() returns 0 instead of ERR_PTR(ret) on error, so
callers checking IS_ERR() see a failed registration as success.

Fixes: 9eb9f0004347 ("CLK: Add support for composite clock from Linux kernel")
