Subject: [PATCH] hwrng: omap3-rom - fix using wrong clk_disable() in omap_rom_rng_runtime_resume()
Git-commit: e4e62bbc6aba49a5edb3156ec65f6698ff37d228
Patch-mainline: v5.19-rc1
References: git-fixes
'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")
