Subject: [PATCH net] net: phy: marvell-88q2xxx: Fix clamped value in mv88q2xxx_hwmon_write
Date: Tue,  2 Dec 2025 18:27:44 +0100	[thread overview]
Message-ID: <20251202172743.453055-3-thorsten.blum@linux.dev> (raw)

The local variable 'val' was never clamped to -75000 or 180000 because
the return value of clamp_val() was not used. Fix this by assigning the
clamped value back to 'val', and use clamp() instead of clamp_val().

Cc: stable@vger.kernel.org
Fixes: a557a92e6881 ("net: phy: marvell-88q2xxx: add support for temperature sensor")
