Subject: [PATCH] hgafb: fix probe function
Date: Mon, 17 May 2021 11:50:32 +0300	[thread overview]
Message-ID: <YKIuWEcIJvTIuE2j@mwanda> (raw)

There is a reversed if statement in this probe function so the driver is
completely broken.

Fixes: dc13cac4862c ("video: hgafb: fix potential NULL pointer dereference")
Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com>
