Hi Imededdine.

Just some simple notes.

Your subject line doesn't match the patch and
you are doing more than a single brace change.

There are lots of whitespace changes.

Maybe multiple patches for easier review would be better.

These might as well be expanded in-place.

This CHECKAUDIO #define isn't used anywhere and could
be deleted.

Please be consistent with with multi-line statement
indentation.

If this is really an 80 column problem (and if it is,
it's a small one), please use alignment to open paren
like:

static int cdrom_get_disc_info(struct cdrom_device_info *cdi,
disc_information *di);

(maximal 8 indent tabs, spaces remainder)

etc...
