[yocto] [meta-raspberrypi][PATCH 2/5] rpi-config: Allow to mask GPU irqs
From: Derek Foreman der...@osg.samsung.com
The rpi config.txt file has a mask_gpu_interrupt option which needs to
be set when using the new VC4 DRM/KMS driver. Since this option exists
in the config file and needed by some kernels, add a option to set it.
