Cool. Looks like the patch needs to be formatted with tabs,
see Documentation/Submit* files.

Then run scripts/checkpatch.pl --strict /path/to/your/patch
on each of them to check for obvious issues :)

Then resend the patches to the related mailing lists:

To linux-omap list:

1. This patch reformatted
2. Defconfig

To linux-input list with linux-omap Cc'd:
3. ...
4. ...

To alsa-devel list with linux-omap Cc'd:
5. ...

Please see the MAINTAINERS file for the file paths of the
maintainers and mailing lists.

Regards,

Tony
