Kernel source files need not include <linux/kconfig.h> explicitly because the top Makefile forces to include it with: -include $(srctree)/include/linux/kconfig.h This commit removes explicit includes except the following: * arch/s390/include/asm/facilities_src.h * tools/testing/radix-tree/linux/kernel.h These two are used for host programs.

2016-09-19[media] Input: synaptics-rmi4: disallow impossible configurationArnd Bergmann1-1/+1
The newly added debug mode for the synaptics-rmi4 driver relies on the v4l2 interface and vb2_vmalloc, but those might be configured as loadable modules when the driver itself is built-in, resulting in a link failure: drivers/input/rmi4/rmi_core.o: In function `rmi_f54_remove': rmi_f54.c:(.text.rmi_f54_remove+0x14): undefined reference to `video_unregister_device' rmi_f54.c:(.text.rmi_f54_remove+0x20): undefined reference to `v4l2_device_unregister' drivers/input/rmi4/rmi_core.o: In function `rmi_f54_vidioc_s_input': rmi_f54.c:(.text.rmi_f54_vidioc_s_input+0x10): undefined reference to `video_devdata' drivers/input/rmi4/rmi_core.o: In function `rmi_f54_vidioc_g_input': rmi_f54.c:(.text.rmi_f54_vidioc_g_input+0x10): undefined reference to `video_devdata' drivers/input/rmi4/rmi_core.o: In function `rmi_f54_vidioc_fmt': rmi_f54.c:(.text.rmi_f54_vidioc_fmt+0x10): undefined reference to `video_devdata' drivers/input/rmi4/rmi_core.o: In function `rmi_f54_vidioc_enum_input': rmi_f54.c:(.text.rmi_f54_vidioc_enum_input+0x10): undefined reference to `video_devdata' drivers/input/rmi4/rmi_core.o: In function `rmi_f54_vidioc_querycap': ...

2016-07-14Input: synaptics-rmi4 - use of_get_child_by_name() to fix refcountAndrew Duggan1-2/+2
Calling of_find_node_by_name() assumes that the caller has incremented the refcount of the of_node being passed in. Currently, the caller is not incrementing the refcount of the of_node which results in the node being prematurely freed when of_find_node_by_name() calls of_node_put() on it. Instead use of_get_child_by_name() which does not call put on the of_node. Signed-off-by: Andrew Duggan <aduggan@synaptics.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>

Synaptics uses the Register Mapped Interface (RMI) protocol as a communications interface for their devices. This driver adds the core functionality needed to interface with RMI4 devices. RMI devices can be connected to the host via several transport protocols and can supports a wide variety of functionality defined by RMI functions. Support for transport protocols and RMI functions are implemented in individual drivers. The RMI4 core driver uses a bus architecture to facilitate the various combinations of transport and function drivers needed by a particular device.
