Subject: [PATCH 02/63] ide-cd: fix ACER/AOpen 24X CDROM speed reporting on big-endian machines
Date: Thu, 20 Dec 2007 01:51:39 +0100 [thread overview]
Message-ID: <200712200151.39973.bzolnier@gmail.com> (raw)
* Fix ACER/AOpen 24X CDROM speed reporting on big-endian machines
by adding missing le16_to_cpu() calls.
While at it:
* Replace ntohs() by be16_to_cpu().
