2018-02-19drm/radeon: use raw buffer printk specifierDmitry Rozhkov
printk format strings accepting a single subsequent argument are shorter thus easier to read. Instead of having format strings accepting 3 different arguments pointing to first 3 bytes of the same buffer rewrite the format string to accept only one argument - the buffer - with "%3ph" specifier.

2018-02-19drm/edid: Add 6 bpc quirk for CPT panel in Asus UX303LAKai-Heng Feng
Similar to commit e10aec652f31 ("drm/edid: Add 6 bpc quirk for display AEO model 0."), the EDID reports "DFP 1.x compliant TMDS" but it support 6bpc instead of 8 bpc. Hence, use 6 bpc quirk for this panel.

The compiler is not automatically caching the i915->regs address inside a register and emitting a load for every mmio access.

2018-02-19drm/i915: Remove WARN_ONCE for failing to pm_runtime_if_in_useChris Wilson
As the driver is called to handle circumstances beyond it's control, we cannot assume that the pm_runtime core is happy to see us. For example, if we are called from shrink_slab to free up our pages during suspend, rpm may be disabled and pm_runtime_if_in_use() decides to fail with -EINVAL rather than simply say no. This is expected to happen, so don't warn.

2018-02-19drm: Use idr_init_base(1) when using id==0 for invalidChris Wilson
Use the new idr_init_base() function to create an IDR that knows id==0 is never allocated as it maps to an invalid identifier. By knowing that id==0 is invalid, the IDR can start from id=1 instead avoiding the issue of having to start each lookup from the zeroth leaf as id==0 is always unused (and thus the tree-of-bitmaps indicate that is the first available).

2018-02-18drm/rockchip: Respect page offset for PRIME mmap callsØrjan Eide
When mapping external DMA-bufs through the PRIME mmap call, we might be given an offset which has to be respected. However for the internal DRM GEM mmap path, we have to ignore the fake mmap offset used to identify the buffer only. Currently the code always zeroes out vma->vm_pgoff, which breaks the former. This patch fixes the problem by moving the vm_pgoff assignment to a function that is used only for GEM mmap path, so that the PRIME path retains the original offset.

2018-02-16drm: Allow determining if current task is output poll workerLukas Wunner
Introduce a helper to determine if the current task is an output poll worker. This allows us to fix a long-standing deadlock in several DRM drivers wherein the ->runtime_suspend callback waits for the output poll worker to finish and the worker in turn calls a ->detect callback which waits for runtime suspend to finish. The ->detect callback is invoked from multiple call sites and waiting for runtime suspend to finish is the correct thing to do except if it's executing in the context of the worker. v2: Expand kerneldoc to specifically mention deadlock between output poll worker and autosuspend worker as use case.

2018-02-16drm/nouveau: Make clock gate support conditionalThierry Reding
The recently introduced clock gate support breaks on Tegra chips because no thermal support is enabled for those devices. Conditionalize the code on the existence of thermal support to fix this.

Register Address for CNL_PORT_DW5_LN0_D is 0x162E54, but current code is defining it as 0x162ED4. Similarly for CNL_PORT_DW7_LN0_D register address is defined 0x162EDC instead of 0x162E5C, fix it.
