Subject: Generic DMA - BUG_ON
Date: Wed, 20 Jan 2010 11:08:30 +0100	[thread overview]
Message-ID: <1263982111-24123-1-git-send-email-monstr@monstr.eu> (raw)

Hi All,

I have this patch in my repo. I just added BUG_ON for dma ops.
The reason for that is if driver not setup ops correctly than
the system do bad access to any memory space without any visible reason.
BUG_ON points to it and helps to solve where the problem is.

Thanks for your review,
Michal
