Subject: [PATCH] thermal/core: Remove pointless variable when registering a cooling device
Date: Thu,  2 Apr 2026 10:44:25 +0200	[thread overview]
Message-ID: <20260402084426.1360086-1-daniel.lezcano@kernel.org> (raw)

From: Daniel Lezcano <daniel.lezcano@oss.qualcomm.com>

The 'id' variable is set to store the ida_alloc() value which is
already stored into cdev->id. It is pointless to use it because
cdev->id can be used instead.
