- 950-0421-HID-hid-bigbenff-driver-for-BigBen-Interactive-PS3OF.patch
- 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 406/454] staging: bcm2835-camera: Handle empty EOS buffers
+ whilst streaming
+
+The change to mapping V4L2 to MMAL buffers 1:1 didn't handle
+the condition we get with raw pixel buffers (eg YUV and RGB)
+direct from the camera's stills port. That sends the pixel buffer
+and then an empty buffer with the EOS flag set. The EOS buffer
+wasn't handled and returned an error up the stack.
+
+Handle the condition correctly by returning it to the component
+if streaming, or returning with an error if stopping streaming.
+
+Fixes: 9384167 "staging: bcm2835-camera: Remove V4L2/MMAL buffer remapping"
