Hi Bruce and Michal,
Please help review and merge this 2 patches.
And these 2 issues are also in linux-xlnx master branch.
I assume that you'll also submit the changes to the xilinx git as
well ? Once we agree on that they are correct, of course :D
I won't submit them to xilinx git tree. Michal may decide if these changes
can be submitted to xilinx git.
Thanks,
Quanyang
I've staged them here, since I want to get things collected for
testing against some new -stable updates.
If there's review feedback, I can revert and update or do an
incremental change.

1) The patch "drm: xlnx: bridge: check bridge->debugfs_file->status when
calling strlen" fixes the issue that kernel crash as below:
root@xilinx-zynqmp:/sys/kernel/debug/xlnx-bridge# cat xlnx_bridge-display.gfx
After applying this patch, it will not crash anymore but just show
nothing.
2) The patch "drm: xlnx: zynqmp: tpg should use swap_coeffs as csc matrix"
fixes the issue that tpg is outputing in a wrong color and this issue
can be reproduced by the steps as below:
root@xilinx-zynqmp:~# modetest -D fd4a0000.display -w 40:alpha:0
trying to open device 'i915'...done
root@xilinx-zynqmp:~# modetest -D fd4a0000.display -w 39:tpg:1
trying to open device 'i915'...done
Thanks,
Quanyang
