Merge tag 'topic/core-stuff-2014-12-19' of git://anongit.freedesktop.org/drm-intel into drm-next
Misc drm patches with mostly polish patches from Thierry, with a bit of generic mode validation from Ville and a few other oddball things. * tag 'topic/core-stuff-2014-12-19' of git://anongit.freedesktop.org/drm-intel: (25 commits) drm: Include drm_crtc_helper.h in DocBook drm: Make drm_crtc_helper.h standalone includible drm: Move IRQ related fields to proper section drm: Remove stale comment drm: Do basic sanity checks for user modes drm: Perform basic sanity checks on probed modes drm: Reorganize probed mode validation drm/doc: Remove duplicate "by" drm/info: Remove unused code drm/cache: Use wbinvd helpers drm/plane-helper: Test for plane disable earlier drm/doc: Document drm_add_modes_noedid() usage drm: bit of spell-check / editorializing. drm: Prefer sizeof(type) over sizeof type drm: Remove useless else block drm: Remove unneeded braces for single statement blocks drm: Do not assign in if condition drm: Prefer kmalloc_array() over kmalloc() with multiply drm: Prefer kcalloc() over kzalloc() with multiply drm: Miscellaneous checkpatch whitespace cleanups ...
