Add the supply mappings and you should be fine. This should have been done when the device was added, the commit doing that looks like it was never tested in mainline as the driver problem was fixed in October 2011 but the RX51 didn't start using the device until May 2012. --z+pzSjdB7cqptWpS Content-Type: application/pgp-signature; name="signature.asc" Content-Description: Digital signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iQIcBAEBAgAGBQJRIR7MAAoJELSic+t+oim9/jUP/jjGHqoCYbuRWdZeDeAHZzZ4 GZlZfb+nkgCiWcTHe6tYVhgUe47TO6yHf9eHLVOw1g/LY4BYxAXfSX2nC0avbloH VEDJfmK4fskGvb2jEdBmYuZg/EiugCjUT7KtUOg1CQDBKRf8eWbtqUWgArumiF5x jhHdDVyf9fQaGAM/kjAoNyxSCp7wyi3Z3Ax/pHUBtCnAnH1SN4CKPY8rFl0cyIUl pZNgRPADKHwcxBO7SFBtgNU5gaIhWixrvmDYbjMJEHmdQXt91e3UxTuMeljkeXn7 gTvw98J+9Jp2B/qa4/0fv4hni4CbhAHlYTWhzOL/aO71vZ2DcnjUKBcu3qkqRxdd s6yF+qTWCZRFYTYNeFAc4h39aXZnZ3LfPXVyHo9OlMgv0u4fDQTXc2UW5mjZO4fz lJabqQ47KxbOMHTvjNmp/N1jLRWSYlL20eGScvajIqR5eI/MxeT7/VQaNADFxcFr z4iklswpI08dw/GxfC8DNZaSx4vnXaIWnKBwI0Cx0jQtEGiGfRTXCOxGea/PirNP o2BLAGZ952wRqsrrTJBXJvnGqd8Pyios+2ZpvEdGY1BZzFI2pb3scfAydil0VFBa NC4jZlT/dPARfYdMgWZa5Hhj+UYqYuIS0LCOHVigndxix6vdr5fiPHXVNxFGqGjO wtjZXufl7W98ltqy1aUo =p2sk -----END PGP SIGNATURE----- --z+pzSjdB7cqptWpS--
