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 Signed-off-by: Stijn Tintel <stijn@linux-ipv6.be>

Subject: [PATCH 127/454] panel-raspberrypi-touchscreen: Fix NULL deref if
|
|
probe order goes wrong.
|
|
|
|
If the i2c driver hadn't pobed before the panel driver probes, then
|
|
the client would be NULL but we were looking for an ERR_PTR in the
|
|
error case.
