After being asked to not depend on ARCH_QCOM* or similar,
unsurprisingly compilation fails on UM as it has no I/O
memory:
drivers/built-in.o: In function `qcom_ebi2_probe':
>> drivers/bus/qcom-ebi2.c:333: undefined reference to
`devm_ioremap_resource'
Fix this by letting the Kconfig atleast depend on HAS_IOMEM.

The gpiochip_free_own_desc() function tests whether its argument is NULL
and then returns immediately. Thus the test around the call is not needed.
This issue was detected by using the Coccinelle software.

Pull drm fixes from Dave Airlie:
"A bunch of fixes covering i915, amdgpu, one tegra and some core DRM
ones. Nothing too strange at this point"
* tag 'drm-fixes-for-4.8-rc4' of git://people.freedesktop.org/~airlied/linux: (21 commits)
drm/atomic: Don't potentially reset color_mgmt_changed on successive property updates.
drm: Protect fb_defio in drivers with CONFIG_KMS_FBDEV_EMULATION
drm/amdgpu: skip TV/CV in display parsing
drm/amdgpu: avoid a possible array overflow
drm/amdgpu: fix lru size grouping v2
drm/tegra: dsi: Enhance runtime power management
drm/i915: Fix botched merge that downgrades CSR versions.
drm/i915/skl: Ensure pipes with changed wms get added to the state
drm/i915/gen9: Only copy WM results for changed pipes to skl_hw
drm/i915/skl: Add support for the SAGV, fix underrun hangs
drm/i915/gen6+: Interpret mailbox error flags
drm/i915: Reattach comment, complete type specification
drm/i915: Unconditionally flush any chipset buffers before execbuf
drm/i915/gen9: Drop invalid WARN() during data rate calculation
drm/i915/gen9: Initialize intel_state->active_crtcs during WM sanitization (v2)
drm: Reject page_flip for !DRIVER_MODESET
drm/amdgpu: fix timeout value check in amd_sched_job_recovery
drm/amdgpu: fix sdma_v2_4_ring_test_ib
drm/amdgpu: fix amdgpu_move_blit on 32bit systems
drm/radeon: fix radeon_move_blit on 32bit systems
...
Due to assigning the 'replaced' value instead of or'ing it,
if drm_atomic_crtc_set_property() gets called multiple times,
the last call will define the color_mgmt_changed flag, so
a non-updating call to a property can reset the flag and
prevent actual hw state updates required by preceding
property updates.
