Fixes for omapdrm, some of which were already present in 3.14, and some which
appeared in 3.15-rc1: - fixes for primary-plane handling which caused crashes - fix all kinds of uninit issues which prevented from unloading the omapdrm module. - fixes for HDMI enable/disable issues -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.14 (GNU/Linux) iQIcBAABAgAGBQJTTkM7AAoJEPo9qoy8lh71JaQP/2NvUIr64vCXd39FqzrpwJ2n iRwHFt0M5sHld6NCNVyaThQtmRAN7u7fkInwcUWPU1yv0HIkHB2CRAzTx3H1Ca73 S+eaqda6Rog2oGh/Q6xmpAjaxZX0td9QhhGfKm9MlNJQ/a50H/7ovq5XZu2etfj2 m1nW6L1U+43aZYDLjM6T6IOydqWZGZ0jv6sNOAa4vwWWIJ85y+MybL2AL6SOQXpR LLbe/wI6eMBguJQOiLfZivFtlF7HzvT9I/VRhrtL+aanBOqVeqEFEcxJhutIl8/g NOZo+XfeRJqGJ5FDbgwFqP/+sDQEKQBHL+9/XfUVdJmKI3ihyhF5o4jCPpkHqYTP S3hyxQOkPZ/wgP8ucG0BvzhQRZoatSyIUbDE/98etmZ2pqLXk6d+tRs2uAev/0ec WLDc8/JEbTOE9cG/VAqVZTPsucuoWZ8Ow70v65ZlloqiaD/6QAWigavcQA1EZO+F cHBuwNXXAu8b2VV1cQcQVbihhga7lt1RFIzr7hQpniERK7tqeVqgapLWruxEJ5HZ 9HTRR+JIUydbXjsr0RtY3KIAKhKyfUiEAn7YIZBPpR7jSlUiexbX2ZrBN4Ea+sst Kjs/I71KN6j7lI3hh3R+HKOeYw9wqXuoqtojCafx2JRMEMhiSpOrAZuOjsW0fWSD AJhzTX8ZiFGFOB/oGdwp =03GJ -----END PGP SIGNATURE----- Merge tag 'omapdrm-fixes-3.15' of git://git.kernel.org/pub/scm/linux/kernel/git/tomba/linux into drm-next Fixes for omapdrm, some of which were already present in 3.14, and some which appeared in 3.15-rc1: - fixes for primary-plane handling which caused crashes - fix all kinds of uninit issues which prevented from unloading the omapdrm module. - fixes for HDMI enable/disable issues * tag 'omapdrm-fixes-3.15' of git://git.kernel.org/pub/scm/linux/kernel/git/tomba/linux: drm/omap: fix the handling of fb ref counts drm/omap: protect omap_crtc's event with event_lock spinlock drm/omap: Use old_fb to synchronize between successive page flips drm/omap: Fix crash when using LCD3 overlay manager drm/omap: gem sync: wait on correct events drm/omap: Fix memory leak in omap_gem_op_async drm/omap: remove warn from debugfs drm/omap: remove extra plane->destroy from crtc destroy drm/omap: print warning when rotating non-TILER fb drm/omap: fix missing unref to fb's buf object drm/omap: fix plane rotation drm/omap: fix enabling/disabling of video pipeline drm/omap: fix missing disable for unused encoder drm/omap: fix race issue when unloading omapdrm drm/omap: fix DMM driver (un)registration drm/omap: fix uninit order in pdev_remove() drm/omap: fix output enable/disable sequence
