[PATCH AUTOSEL 4.4 04/13] ARM: dts: logicpd-torpedo-som: Remove twl_keypad

[Sasha Levin]

From: Adam Ford <aford173@gmail.com>

[ Upstream commit 6b512b0ee091edcb8e46218894e4c917d919d3dc ]

The TWL4030 used on the Logit PD Torpedo SOM does not have the
keypad pins routed.  This patch disables the twl_keypad driver
to remove some splat during boot:

twl4030_keypad 48070000.i2c:twl@48:keypad: missing or malformed property linux,keymap: -22
twl4030_keypad 48070000.i2c:twl@48:keypad: Failed to build keymap
twl4030_keypad: probe of 48070000.i2c:twl@48:keypad failed with error -22

[PATCH AUTOSEL 4.4 11/13] of: unittest: fix memory leak in unittest_data_add

[Sasha Levin]

From: Navid Emamdoost <navid.emamdoost@gmail.com>

[ Upstream commit e13de8fe0d6a51341671bbe384826d527afe8d44 ]

In unittest_data_add, a copy buffer is created via kmemdup. This buffer
is leaked if of_fdt_unflatten_tree fails. The release for the
unittest_data buffer is added.

Fixes: b951f9dc7f25 ("Enabling OF selftest to run without machine's devicetree")
