Subject: Re: [PATCH RESEND 6/6] clk: s5p-g2d: Fix incorrect usage of IS_ERR_OR_NULL
Date: Thu, 3 Jan 2013 14:10:40 +0300	[thread overview]
Message-ID: <20130103111040.GD7247@mwanda> (raw)

Come on...  Don't say we haven't read comment.  Obviously, the first
thing we did was read that comment.  I've read it many times at this
point and I still think we should add in a bit which says:

"NOTE:  Drivers should treat the return value as an opaque cookie
and not dereference it.  NULL returns don't imply an error so don't
use IS_ERR_OR_NULL() to check for errors."

regards,
dan carpenter
