Subject: [dmraid 3/4] Fix min/max macros
Date: Thu, 17 Dec 2009 16:44:13 +1100	[thread overview]
Message-ID: <20091217054526.545361172@suse.de> (raw)
In-Reply-To: 20091217054410.410634166@suse.de

[-- Attachment #1: remove-min-max --]
[-- Type: text/plain, Size: 718 bytes --]

These need parentheses around them.

In particular, in hpt37x.c, in 'to_cpu'
we have an expression:
   x + min(y,z)
which will become

 x + y > z ? y : z

which is not what is wanted.
