[PATCH 5.10 309/452] hwrng: omap3-rom - fix using wrong clk_disable() in omap_rom_rng_runtime_resume()

[Greg Kroah-Hartman]

From: Yang Yingliang <yangyingliang@xxxxxxxxxx>

[ Upstream commit e4e62bbc6aba49a5edb3156ec65f6698ff37d228 ]

'ddata->clk' is enabled by clk_prepare_enable(), it should be disabled
by clk_disable_unprepare().

Fixes: 8d9d4bdc495f ("hwrng: omap3-rom - Use runtime PM instead of custom functions")
