git://anongit.freedesktop.org/drm-intel into drm-next Refcounting is hard, so here's a quick pull request with the one-liner to fix up i915. Otherwise just a few other small things I picked up. Plus the regression fix from Marten for rmfb behaviour that lingered around forever since no testers. Feel free to cherry-pick that over to drm-fixes, but given that there's not many who seemed to have cared, meh. * tag 'topic/drm-misc-2016-05-08' of git://anongit.freedesktop.org/drm-intel: drm/i915: Correctly refcount connectors in hw state readou drm/panel: Flesh out kerneldoc drm: Add gpu.tmpl docbook to MAINTAINERS entry drm/core: Do not preserve framebuffer on rmfb, v4. drm: Fix up markup fumble drm/fb_helper: Fix a few typos
2016-05-06drm/i915: Correctly refcount connectors in hw state readouDaniel Vetter
This was forgotten when adding the the refcounting to drm_connector_state. v2: Don't forget to unreference existing connectors. This isn't relevant on driver load, but this code also runs on resume, and there we already have an atomic state. Spotted by Chris Wilson.

2016-05-05drm/fsl-dcu: use bus_flags for pixel clock polarityStefan Agner
The drivers current default configuration drives the pixel data on rising edge of the pixel clock. However, most display sample data on rising edge... This leads to color shift artefacts visible especially at edges. This patch changes the relevant defines to be useful and actually set the bits, and changes pixel clock polarity to drive the pixel data on falling edge by default. The patch also adds an explicit pixel clock polarity flag to the display introduced with the driver (NEC WQVGA "nec,nl4827hc19-05b") using the new bus_flags field to retain the initial behavior.

2016-05-05drm: introduce bus_flags in drm_display_infoStefan Agner
Introduce bus_flags to specify display bus properties like signal polarities. This is useful for parallel display buses, e.g. to specify the pixel clock or data enable polarity.

2016-05-05drm/core: Do not preserve framebuffer on rmfb, v4.Maarten Lankhorst
It turns out that preserving framebuffers after the rmfb call breaks vmwgfx userspace. This was originally introduced because it was thought nobody relied on the behavior, but unfortunately it seems there are exceptions. drm_framebuffer_remove may fail with -EINTR now, so a straight revert is impossible. There is no way to remove the framebuffer from the lists and active planes without introducing a race because of the different locking requirements. Instead call drm_framebuffer_remove from a workqueue, which is unaffected by signals. Changes since v1: - Add comment. Changes since v2: - Add fastpath for refcount = 1. (danvet) Changes since v3: - Rebased. - Restore lastclose framebuffer removal too. Cc: stable@vger.kernel.org #v4.4+ Fixes: 13803132818c ("drm/core: Preserve the framebuffer after removing it.")

2016-05-04drm/amdgpu: Replace rcu_assign_pointer() with RCU_INIT_POINTER()Muhammad Falak R Wani
The rcu_assign_pointer() ensures that the initialization of a structure is carried out before storing a pointer to that structre. It is always safe to use RCU_INIT_POINTER() to NULL a pointer, instead of rcu_assign_pointer(). This results in slightly smaller/faster code.
