[PATCH 5.17 0052/1126] firmware: sysfb: fix platform-device leak in error path

[Greg Kroah-Hartman]

From: Johan Hovold <johan@xxxxxxxxxx>

commit 202c08914ba50dd324e42d5ad99535a89f242560 upstream.

Make sure to free the platform device also in the unlikely event that
registration fails.

Fixes: 0589e8889dce ("drivers/firmware: Add missing platform_device_put() in sysfb_create_simplefb")
Fixes: 8633ef82f101 ("drivers/firmware: consolidate EFI framebuffer setup for all arches")
