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
