Pull drm fixes from Dave Airlie: "Usual pull request, little larger than I'd like but nothing too strange in it. Willy found an bug in the lease ioctl calculations, but it's a drm master only ioctl which makes it harder to mess with. i915: - combo phy programming fix - opregion version check fix for VBT RVDA lookup - gem mmap ioctl race fix - fbdev hpd during suspend fix - array size bounds check fix in pmu amdgpu: - Vega20 psp fix - Add vrr range to debugfs for freesync debugging sched: - Scheduler race fix vkms: - license header fixups imx: - Fix CSI register offsets for i.MX51 and i.MX53. - Fix delayed page flip completion events on i.MX6QP due to unexpected behaviour of the PRE when issuing NOP buffer updates to the same buffer address. - Stop throwing errors for plane updates on disabled CRTCs when a userspace process is killed while a plane update is pending. - Add missing of_node_put cleanup in imx_ldb_bind" * tag 'drm-fixes-2019-02-15-1' of git://anongit.freedesktop.org/drm/drm: drm: Use array_size() when creating lease drm/amdgpu/psp11: TA firmware is optional (v3) drm/i915/opregion: rvda is relative from opregion base in opregion 2.1+ drm/i915/opregion: fix version check drm/i915: Prevent a race during I915_GEM_MMAP ioctl with WC set drm/i915: Block fbdev HPD processing during suspend drm/i915/pmu: Fix enable count array size and bounds checking drm/i915/cnl: Fix CNL macros for Voltage Swing programming drm/i915/icl: combo port vswing programming changes per BSPEC drm/vkms: Fix license inconsistent drm/amd/display: Expose connector VRR range via debugfs drm/sched: Always trace the dependencies we wait on, to fix a race. gpu: ipu-v3: pre: don't trigger update if buffer address doesn't change gpu: ipu-v3: Fix CSI offsets for imx53 drm/imx: imx-ldb: add missing of_node_puts gpu: ipu-v3: Fix i.MX51 CSI control registers offset drm/imx: ignore plane updates on disabled crtcs

print("""Usage: diffconfig [-h] [-m] [<config1> <config2>]
Diffconfig is a simple utility for comparing two .config files.
Using standard diff to compare .config files often includes extraneous and
distracting information. This utility produces sorted output with only the
changes in configuration values between the two files.
Added and removed items are shown with a leading plus or minus, respectively.
Changed items show the old and new values on a single line.
If -m is specified, then output will be in "merge" style, which has the
changed and new values in kernel config option format.
If no config files are specified, .config and .config.old are used.
Example usage:
$ diffconfig .config config-with-some-changes
-EXT2_FS_XATTR n
CRAMFS n -> y
EXT2_FS y -> n
LOG_BUF_SHIFT 14 -> 16
PRINTK_TIME n -> y
