Subject: [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)
In-Reply-To: <20130103100000.GJ2631@n2100.arm.linux.org.uk>
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
