From: Daniel Vetter Date: Thu, 23 Jan 2014 14:35:24 +0000 (+0100) Subject: drm: move drm_mode related functions into drm_modes.c X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8bd441b27e85834533df26a7f1c2c9289303c5ef;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git drm: move drm_mode related functions into drm_modes.c Makes more sense and gives better grouping in the DocBook function reference sections. To make this possible we need to expose two functions from drm_crtc.c though. To avoid further namespace pollution in the system wide headers create a new internal header for such drm internal symbols. I expect that longer-term we'll add tons more, but since my goal here is to polish the kerneldoc that's for another day.
