CVE-2026-46239: media: i2c: ov5647: Fix runtime PM refcount leak in s_ctrl

[Greg Kroah-Hartman]

From: Greg Kroah-Hartman <gregkh@kernel.org>

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.

The Linux kernel CVE team has assigned CVE-2026-46239 to this issue.

Mitigation
==========

The Linux kernel CVE team recommends that you update to the latest
stable kernel version for this, and many other bugfixes.  Individual
changes are never tested alone, but rather are part of a larger kernel
release.  Cherry-picking individual commits is not recommended or
supported by the Linux kernel community at all.  If however, updating to
the latest release is impossible, the individual changes to resolve this
issue can be found at these commits:
