[Intel-gfx] [PATCH 09/23] drm: Remove struct drm_driver.get_scanout_position()

[Thomas Zimmermann]

All users of struct drm_driver.get_scanout_position() have been
covnerted to the respective CRTC helper function. Remove the callback
from struct drm_driver.

-	 * @get_scanout_position:
-	 *
-	 * Called by vblank timestamping code.
-	 *
-	 * Returns the current display scanout position from a crtc, and an
-	 * optional accurate ktime_get() timestamp of when position was
-	 * measured. Note that this is a helper callback which is only used if a
-	 * driver uses drm_calc_vbltimestamp_from_scanoutpos() for the
-	 * @get_vblank_timestamp callback.
-	 *
-	 * Parameters:
-	 *
-	 * dev:
-	 *     DRM device.
-	 * pipe:
-	 *     Id of the crtc to query.
-	 * in_vblank_irq:
-	 *     True when called from drm_crtc_handle_vblank().  Some drivers
-	 *     need to apply some workarounds for gpu-specific vblank irq quirks
-	 *     if flag is set.
-	 * vpos:
-	 *     Target location for current vertical scanout position.
-	 * hpos:
-	 *     Target location for current horizontal scanout position.
-	 * stime:
-	 *     Target location for timestamp taken immediately before
-	 *     scanout position query. Can be NULL to skip timestamp.
-	 * etime:
-	 *     Target location for timestamp taken immediately after
-	 *     scanout position query. Can be NULL to skip timestamp.
-	 * mode:
-	 *     Current display timings.
-	 *
-	 * Returns vpos as a positive number while in active scanout area.
-	 * Returns vpos as a negative number inside vblank, counting the number
-	 * of scanlines to go until end of vblank, e.g., -1 means "one scanline
-	 * until start of active scanout / end of vblank."
-	 *
-	 * Returns:
-	 *
-	 * True on success, false if a reliable scanout position counter could
-	 * not be read out.
-	 *
-	 * This is deprecated and should not be used by new drivers.
-	 * Use &drm_crtc_helper_funcs.get_scanout_position instead.
