Florian Fainelli bb39b8d99a brcm2708: update against latest rpi-3.10.y branch 
Update our copies of the brcm2708 patches to the latest rpi-3.10-y
rebased against linux-3.10.y stable (3.10.32). This should hopefully
make it easier for us in the future to leverage the raspberry/rpi-*
branches.

Subject: [PATCH 145/174] vc_mem: tidy up debug printing
Replace explicit use of printk() with pr_XXX() calls to
better conform to kernel coding style.
