Subject: [PATCH] media: au0828: fix a NULL vs IS_ERR() check
Date: Fri, 14 May 2021 17:20:38 +0300 [thread overview]
Message-ID: <YJ6HNj0g3UlJ6js0@mwanda> (raw)
The media_device_usb_allocate() function returns error pointers when
it's enabled and something goes wrong. It can return NULL as well, but
only if CONFIG_MEDIA_CONTROLLER is disabled so that doesn't apply here.
Fixes: 812658d88d26 ("media: change au0828 to use Media Device Allocator API")
