Subject: [PATCH 05/10] platform/x86: toshiba_acpi: register backlight with device-managed variant
Date: Wed, 24 Mar 2021 14:55:43 +0200	[thread overview]
Message-ID: <20210324125548.45983-6-aardelean@deviqon.com> (raw)
In-Reply-To: <20210324125548.45983-1-aardelean@deviqon.com>

This change converts the registration of the backlight data with the
devm_backlight_device_register() function.
This way, the backlight_device_unregister() call is no longer required, and
the order of deregistration is made to be more symmetrical with the
registration order.
