[PATCH AUTOSEL 4.19 12/22] video: fbdev: simplefb: Check before clk_put() not needed

From: Sasha Levin

From: Yihao Han <hanyihao@xxxxxxxx>

[ Upstream commit 5491424d17bdeb7b7852a59367858251783f8398 ]

clk_put() already checks the clk ptr using !clk and IS_ERR()
so there is no need to check it again before calling it.
