Make the kernel-doc return value agree with both the stub implementation in <linux/clk.h> and the non-stub function in drivers/clk/clk.c.
Signed-off-by: Randy Dunlap <rdunlap@infradead.org> Cc: Russell King <linux@armlinux.org.uk> Cc: linux-clk@vger.kernel.org --- There are several drivers that call clk_get_parent() and use its return value as though it returns an ERR_PTR(). I am working on a patch series to fix those.
