- 950-0453-Add-hid-bigbenff-to-list-of-have_special_driver-for-.patch

Make I2C built-in instead of modular as in upstream defconfig; also the
easiest way to get MFD_ARIZONA enabled, which is required by
kmod-sound-soc-rpi-cirrus.
Add missing compatible strings from
4.9/960-add-rasbperrypi-compatible.patch, using upstream names for
compute modules.
Add extra patch to enable the LEDs on lan78xx.

Compile-tested: bcm2708, bcm2709, bcm2710 (with CONFIG_ALL_KMODS=y)
Runtime-tested: bcm2708, bcm2710

+Subject: [PATCH 113/454] drm/vc4: Fix sending of page flip completion events
+ in FKMS mode.
+
+In the rewrite of vc4_crtc.c for fkms, I dropped the part of the
+CRTC's atomic flush handler that moved the completion event from the
+proposed atomic state change to the CRTC's current state.  That meant
+that when full screen pageflipping happened (glxgears -fullscreen in
+X, compton, por weston), the app would end up blocked firever waiting
+to draw its next frame.
