  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 382/454] staging: vc04_services: remove odd
+ vchiq_debugfs_top() wrapper
+
+commit 2739deaece4bc25fba5df0566423f4a11c3f4e84 upstream
+
+vchiq_debugfs_top() is only a wrapper around a pointer to a dentry, so
+just use the dentry directly instead, making it a static variable
+instead of part of a static structure.
+
+This also removes the pointless BUG_ON() when checking that dentry as no
+one should ever care if debugfs is working or not, and the kernel should
+really not panic over something as trivial as that.
