Subject: [PATCH] platform/x86: intel_pmc_core: fix memleak on registration failure
Date: Wed, 22 Dec 2021 11:50:23 +0100 [thread overview]
Message-ID: <20211222105023.6205-1-johan@kernel.org> (raw)
In case device registration fails during module initialisation, the
platform device structure needs to be freed using platform_device_put()
to properly free all resources (e.g. the device name).
Fixes: 938835aa903a ("platform/x86: intel_pmc_core: do not create a static struct device")
Cc: stable@vger.kernel.org # 5.9
