- 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 175/454] drm/vc4: Fix false positive WARN() backtrace on
+ refcount_inc() usage
+
+With CONFIG_REFCOUNT_FULL enabled, refcount_inc() complains when it's
+passed a refcount object that has its counter set to 0. In this driver,
+this is a valid use case since we want to increment ->usecnt only when
+the BO object starts to be used by real HW components and this is
+definitely not the case when the BO is created.
+
+Fix the problem by using refcount_inc_not_zero() instead of
+refcount_inc() and fallback to refcount_set(1) when
+refcount_inc_not_zero() returns false. Note that this 2-steps operation
+is not racy here because the whole section is protected by a mutex
+which guarantees that the counter does not change between the
+refcount_inc_not_zero() and refcount_set() calls.
+
+Fixes: b9f19259b84d ("drm/vc4: Add the DRM_IOCTL_VC4_GEM_MADVISE ioctl")
