CVE-2026-98661: iio: light: rohm-bu27034: Fix infinite delay on error

[Greg Kroah-Hartman]

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

Description
===========

In the Linux kernel, the following vulnerability has been resolved:

iio: light: rohm-bu27034: Fix infinite delay on error

When reading an integration-time fails, the code will use error code to
compute the sleep time.

Fix this by using the smallest integration time as a default if
reading fails.

The Linux kernel CVE team has assigned CVE-2026-98661 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:
