Subject: [patch] ALSA: cs5535 - Fix an endianness conversion
Date: Sun, 20 Nov 2011 20:57:49 +0000	[thread overview]
Message-ID: <20111120205748.GA7354@elgon.mountain> (raw)

desc->size is supposed to be a le16 type.  On a big endian system the
current code will set ->size to zero.  We fixed a similar bug
on the next line but missed this one.

This is a static checker bug.  I haven't tested it.
