Subject: [PATCH v2 4/7] platform/x86: dell-wmi-sysman: Fix release_attributes_data() getting called twice on init_bios_attributes() failure
Date: Sun, 21 Mar 2021 12:58:58 +0100	[thread overview]
Message-ID: <20210321115901.35072-5-hdegoede@redhat.com> (raw)
In-Reply-To: <20210321115901.35072-1-hdegoede@redhat.com>

All calls of init_bios_attributes() will result in a
goto fail_create_group if they fail, which calls
release_attributes_data().

So there is no need to call release_attributes_data() from
init_bios_attributes() on failure itself.

Fixes: e8a60aa7404b ("platform/x86: Introduce support for Systems Management Driver over WMI for Dell Systems")
