Date: Sun, 08 Nov 2026 17:29:35 +0000 [thread overview]
Message-ID: <sashiko-outbox-203889@kernel.org> (raw)
In-Reply-To: <20261108172651.220121-1-zoone.rupert@gmail.com>
> On 64-bit, update_interval writes are clamped to LONG_MAX ms, but
> ms_to_ktime() overflows above 9223372036854 ms and the interval wraps.
> LONG_MAX becomes -1 ms, so every read starts a new measurement and
> update_interval reads back -1.
>
> Clamp to INT_MAX like sht4x, so the limit is the same on all platforms.
>
> Fixes: 8c78f0dee437 ("hwmon: Add AHT10 Temperature and Humidity Sensor Driver")
