[PATCH] drm/i915/display Try YCbCr420 color when RGB fails

by Werner Sembach

When encoder validation of a display mode fails, retry with less bandwidth heavy YCbCr420 color mode, if available. This enables some HDMI 1.4 setups to support 4k60Hz output, which previously failed silently. AMDGPU had nearly the exact same issue. This problem description is therefore copied from my commit message of the AMDGPU patch. On some setups, while the monitor and the gpu support display modes with pixel clocks of up to 600MHz, the link encoder might not. This prevents YCbCr444 and RGB encoding for 4k60Hz, but YCbCr420 encoding might still be possible. However, which color mode is used is decided before the link encoder capabilities are checked. This patch fixes the problem by retrying to find a display mode with YCbCr420 enforced and using it, if it is valid. I'm not entierly sure if the second "if (HAS_PCH_SPLIT(dev_priv) && !HAS_DDI(dev_priv))" check in intel_hdmi_compute_config(...) after forcing ycbcr420 is necessary. I included it to better be safe then sorry.

[PATCH 66/69] Revert "video: imsttfb: fix potential NULL pointer dereferences"

by Greg Kroah-Hartman

This reverts commit 1d84353d205a953e2381044953b7fa31c8c9702d. Because of recent interactions with developers from @umn.edu, all commits from them have been recently re-reviewed to ensure if they were correct or not. Upon review, this commit was found to be incorrect for the reasons below, so it must be reverted. It will be fixed up "correctly" in a later kernel change. The original commit here, while technically correct, did not fully handle all of the reported issues that the commit stated it was fixing, so revert it until it can be "fixed" fully. Note, ioremap() probably will never fail for old hardware like this, and if anyone actually used this hardware (a PowerMac era PCI display card), they would not be using fbdev anymore.
