** Description changed: IMPACT: During boot, after the rootfs is mounted, the linux-snapdragon kernel prints several lines like these: ...

While both audio and video work fine in the end, these lines make parsing the boot logs harder and might fool a user to think there's a potential problem. FIX: To fix it, make the config DRM_I2C_ADV7511=y. HOW TO REPRODUCE: Boot a patched kernel and check the boot logs.
