Subject: Re: [PATCH] hwmon: (w83627hf) Clamp VRM9 voltage limits before subtracting
Date: Wed, 11 Nov 2026 07:00:52 +0000 [thread overview]
Message-ID: <sashiko-outbox-208481@kernel.org> (raw)
In-Reply-To: <20261111064900.17338-1-zhujun2@cmss.chinamobile.com>
> The VRM9 limit conversion subtracts the 700 mV offset from an unsigned
> value before clamping. Writing zero to in0_min or in0_max therefore
> selects register 255 instead of zero. Multiplication can also wrap for
> large inputs.
>
> Bound the input before applying the VRM9 conversion. The chosen bounds
> cover the full register range and keep the arithmetic within range.

> Fixes: 1da177e4c3f41 ("Linux-2.6.12-rc2")
