Subject: [PATCH RFC 11/11] staging: bcm2835-camera: Add hint about possible faulty config
Date: Thu, 25 Oct 2018 17:29:35 +0200	[thread overview]
Message-ID: <1540481375-15952-12-git-send-email-stefan.wahren@i2se.com> (raw)
In-Reply-To: <1540481375-15952-1-git-send-email-stefan.wahren@i2se.com>

As per default the GPU memory config of the Raspberry Pi isn't sufficient
for the camera usage. Even worse the bcm2835 camera driver doesn't provide a
helpful error message in this case. So let's add a hint to point the user
to the likely cause.
