  MEDIA_SUBDRV_AUTOSELECT
- 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 161/454] ASoC: bcm2835: fix hw_params error when device is in
+ prepared state (#2345)
+
+commit 8d5737a5f53902a916ee1e1cb248c9b8b883b2ea  upstream.
+
+If bcm2835 is configured as bitclock master calling hw_params()
+after prepare() fails with EBUSY. This also makes it impossible to
+use bcm2835 in full duplex mode.
+
+The error is caused by the split clock setup: clk_set_rate
+is called in hw_params, clk_prepare_enable in prepare. As hw_params
+doesn't check if the clock was already enabled clk_set_rate
+fails with EBUSY.
+
+Fix this by moving clock startup from prepare to hw_params and
+let hw_params properly deal with an already set up or enabled
+clock.
