drm: Implement drm_modeset_lock_all_ctx()
This function is like drm_modeset_lock_all(), but it takes the lock acquisition context as a parameter rather than storing it in the DRM device's mode_config structure. Implement drm_modeset_{,un}lock_all() in terms of the new function for better code reuse, and add a note to the kerneldoc that new code should use the new functions. v2: improve kerneldoc v4: rename drm_modeset_lock_all_crtcs() to drm_modeset_lock_all_ctx() and take mode_config's .connection_mutex instead of .mutex lock to avoid lock inversion (Daniel Vetter), use drm_modeset_drop_locks() which is now the equivalent of drm_modeset_unlock_all_ctx() v5: do not take the dev->mode_config.connection_mutex in drm_atomic_legacy_backoff() since drm_modeset_lock_all_ctx() already keeps it, enhance kerneldoc for drm_modeset_lock_all_ctx() (Daniel Vetter) Signed-off-by: Thierry Reding <treding@nvidia.com> Link: http://patchwork.freedesktop.org/patch/msgid/1449075005-13937-1-git-send-email-thierry.reding@gmail.com Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
