CVE-2026-46239
media: i2c: ov5647: Fix runtime PM refcount leak in s_ctrl
Description
In the Linux kernel, the following vulnerability has been resolved: media: i2c: ov5647: Fix runtime PM refcount leak in s_ctrl Three control cases (AUTOGAIN, EXPOSURE_AUTO, ANALOGUE_GAIN) directly return without calling pm_runtime_put(), causing runtime PM reference count leaks. Change these cases from 'return' to 'ret = ... break' pattern to ensure pm_runtime_put() is always called before function exit.
