5.10-stable review patch. If anyone has any objections, please let me know. ------------------ From: Xu Wang <vulab@xxxxxxxxxxx> [ Upstream commit 3fc5a284213d5fca1c0807ea8725355d39808930 ] Because clk_disable_unprepare() already checked NULL clock parameter, so the additional check is unnecessary, just remove them.
