treewide: remove redundant #include

2016-10-11T22:06:33Z

Kernel source files need not include 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.

Input: synaptics-rmi4 - fix error handling in I2C transport driver

2016-10-04T18:52:24Z

Instantiating the rmi4 I2C transport driver without interrupts assigned (for example using manual i2c instantiation from the command line) caused the driver to fail to load, but it does not clean up its regulator or transport device registrations. Result is a crash at a later time, for example when rebooting the system.

[media] Input: synaptics-rmi4: disallow impossible configuration

2016-09-19T19:24:43Z

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': ...
