renesas-drivers-2015-11-24-v4.4-rc2

[Geert Uytterhoeven]

I've pushed renesas-drivers-2015-11-24-v4.4-rc2 to
https://git.kernel.org/cgit/linux/kernel/git/geert/renesas-drivers.git
This tree is meant to ease development of platform support and drivers for
Renesas ARM ("shmobile") SoCs. It's created by merging (a) the for-next 
branches of various subsystem trees and (b) branches with driver code
submitted or planned for submission to maintainers into the development
branch of Simon Horman's renesas.git tree.

Today's version is based on renesas-devel-20151124-v4.4-rc2.

Included branches with driver code:
  - sh-pfc-for-v4.5
  - topic/rcar-dmac-residue-v1
  - topic/rcar-dmac-hamza-v3
  - topic/scif-iommu
  - topic/sci-clk-cleanup-v2

I can't reproduce that. Which version (git commit ID if possible) of modetest 
are you using ?

No, you're testing renesas-devel-20151124-v4.4-rc2.

renesas-drivers-2015-11-24-v4.4-rc2 = 1f9e8ee5963d826af20c7bd70bc3fd997e6a4c7f

Of course. I should have read more than the last 10 characters of the tag... 
Sorry about that.

Crash reproduced, problem fixed, patch sent, you've been CC'ed. I've pushed 
the patch to 

	git://linuxtv.org/pinchartl/fbdev.git drm/next/du

Note that this is a v2 of an unmerged patch, not a fix on top of the drivers 
tree.
