Subject: [PATCH 10/15] staging: bcm2835-camera: Replace BUG_ON with return error
Date: Thu, 10 May 2018 12:42:14 -0700	[thread overview]
Message-ID: <20180510194220.30675-11-eric@anholt.net> (raw)
In-Reply-To: <20180510194220.30675-1-eric@anholt.net>

From: Dave Stevenson <dave.stevenson@raspberrypi.org>

The error conditions don't warrant taking the kernel down, so remove
BUG_ON.
