Subject: [PATCH v2 2/6] iio: adc: ti-ads1015: fix PM leak on probe failure
Date: Tue, 28 Jul 2026 00:50:58 +0530	[thread overview]
Message-ID: <20260727192102.37968-3-architanant5@gmail.com> (raw)
In-Reply-To: <20260727192102.37968-1-architanant5@gmail.com>

If iio_device_register() fails during probe(), the runtime PM
subsystem is left enabled. This leads to a resource leak upon failure.

Add the missing pm_runtime_disable() and pm_runtime_set_suspended()
calls to the probe() error path to ensure proper cleanup.
