Subject: [PATCH 6.1.y] iio: pressure: dps310: fix NULL pointer dereference on ACPI probe
Date: Thu, 10 Sep 2026 22:14:05 -0400 [thread overview]
Message-ID: <20260911021405.42692-1-sashal@kernel.org> (raw)
In-Reply-To: <2026090922-unread-confused-555a@gregkh>
From: Rupesh Majhi <zoone.rupert@gmail.com>
[ Upstream commit 26e9213898fc949923188ef0aeea31fc87708836 ]
When the device is enumerated through its ACPI HID (IFX3100),
i2c_client_get_device_id() returns NULL: the ACPI-derived client name
does not match the driver's i2c_device_id table. dps310_probe() then
dereferences that NULL pointer in "iio->name = id->name" and crashes the
kernel during probe.
The IIO device name is always "dps310", so set it directly and drop the
now-unused device-id lookup.
Fixes: 72ff282819d0 ("iio: pressure: dps310: Add ACPI HID table")
