The document mentions that you have used shmobile_defconfig. However, that 
configuration in v4.8 doesn't enable CONFIG_CMA, which causes at least the DU 
driver to fail probing the device. I thus assume you have modified the 
configuration to enable CMA. The fact that shmobile_defconfig doesn't include 
the uvcvideo driver used by test 14 seems to confirm local modifications to 
the configuration.

It would be useful to attach the kernel .config file to future reports to help 
reproducing the test failures with the exact same configuration.

By the way, while at it, your e-mails are filtered out by the vger.kernel.org 
server as they contain HTML. If you could send future reports without HTML it 
would help them reaching the mailing list archive (although the presence of an 
attachment might not be appreciated by vger.kernel.org, I'm not sure about

Issue 8 ("Lager: bad image quality when shown on HDMI display") can't be 
reproduced on my system when displaying a test pattern with the modetest 
application. Could you please share more information on how to reproduce the 
problem ?

Issue 11 ("VSP1:error message appears on initilization") has been introduced

The fix is available in v4.9-rc1. I've also submitted it for inclusion in the 
v4.8 stable series.

Issue 14 ("USB-CAM: Warning message appears if remove the usb-camera cable 
under using") is likely not a Renesas-specific problem, but as I'm the 
maintainer of the uvcvideo webcam driver you used for testing I'll investigate
