Subject: [PATCH] video: reunite fb devices with their hardware parent
Date: Thu, 27 May 2021 14:44:53 +0200	[thread overview]
Message-ID: <20210527124453.22710-1-a.fatoum@pengutronix.de> (raw)

So far, only sdlfb and efi associated the framebuffer device they
register with the hardware device providing it.

Follow suit for all other frame buffers.  This enables devinfo
to display parentage.
