- 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 201/454] drm/panel: rpi-touchscreen: propagate errors in
+ rpi_touchscreen_i2c_read()
+
+There is one caller which checks whether rpi_touchscreen_i2c_read()
+returns negative error codes.  Currently it can't because negative
+error codes are truncated to u8, but that's easy to fix if we change the
+type to int.
