[PATCH v1] ACPI: video: Clear driver_data pointer on remove

[Rafael J. Wysocki]

From: Rafael J. Wysocki <rafael.j.wysocki@xxxxxxxxx>

After commit 02c057ddefef ("ACPI: video: Convert the driver to a
platform one") the driver_data pointer in the ACPI companion device
object is not cleared automatically on driver remove any more, so
clear it directly in acpi_video_bus_remove().

Fixes: 02c057ddefef ("ACPI: video: Convert the driver to a platform one")
Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@xxxxxxxxx>

Applies on top of the current mainline.
