USB: m66592-udc: fixes some problems
This patch incorporates some updates from the review of the Renesas m66592-udc driver. Updates include: - Fix some locking bugs; and add a few sparse annotations - Don't #define __iomem ! - Lots of whitespace fixes (most of the patch by volume) - Some #include file trimmage - Other checkpatch.pl and sparse updates - Alphabetized and slightly-more-informative Kconfig - Don't use the ID which was assigned to the amd5536udc driver. - Remove pointless suspend/resume methods updating obsolete field. - Some section fixups - Fix some leak bugs - Fix byteswapping Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Yoshihiro Shimoda <shimoda.yoshihiro@renesas.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
