twl-core driver and to fix omap1_defconfig compile when led driver changes and omap sparse IRQ changes are merged together. Also fix warnings for omaps not using pinctrl framework yet. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iQIcBAABAgAGBQJQV9rrAAoJEBvUPslcq6Vz2AEQAIwbb/tKUgxubP6i31fuy/33 rP5RsgEMcnh3lD81+3G3hWECvxkfbs2LM06qi20YG90SPXYVd9koIWil407gvcTQ Nqq+36QBDsQo06ou1Pmy0DeBJ8yo2j3YU+lB6m+Qn7WS+KPqrebt/DMFdMW3Yfc3 zZ87DMfw/5S787z2Uru2CLGLpgv3bOooLvJYv0xBgkKTsRmJGIKJQJ7QoXIQMves 0sLAm/nORu7UU7WvYHd+tU/gC4svfm3WEL+QX4vNvPszCQdTayh7kdZN02eaNLJF vTUNiKjsW/xmda8+XS6YhP6lPFTPoCkDJWrIZqSWFaCnIIpsQZ+IBNdQMiB8uLtR eMdngBqIDTmRo5BOLMM/6eU2yzZ/PLeJI1pMQOTylgz2qaugQEnd77mIzEj6sNVn qSNtAwXTiBEhvA+8cjgsePnJxNtBdwcZ1c8YpEWigFC3cGOl3vHpt0XimIUfrkYX kKMHnVe9WHQGPFXdkA48ZXrACwzrDb1/3GUVbtGM7rX6/OiS6b4iJzplvBN4j1t1 eOH670dVbU2LhkStHhzV2rbQm7LUyVECkn+CGh13VRJDQrVlzA70g6Vp2KBNkgM+ bxyE7sirHHtzeJtFelYGeuRJ1RULAPxPBrVX7kPsrwcSAshKFnuAC6f9IQjCy3jf uYcmix5Qg14mN18H0l6S =omEP -----END PGP SIGNATURE----- Merge tag 'cleanup-fixes-for-v3.7' into test_v3.6-rc6_ocb3.7_cff3.7_odaf3.7 These fixes are needed to fix non-omap build breakage for twl-core driver and to fix omap1_defconfig compile when led driver changes and omap sparse IRQ changes are merged together. Also fix warnings for omaps not using pinctrl framework yet.
