Subject: [PATCH 5.19 0501/1157] media: ov7251: add missing disable functions on error in ov7251_set_power_on()

From: Yang Yingliang <yangyingliang@...wei.com>

[ Upstream commit 7a9795b31049b7e233d050a82b00094155a695c7 ]

Add the missing gpiod_set_value_cansleep() and clk_disable_unprepare()
before return from ov7251_set_power_on() in the error handling case.
