7a4b9a29f8 [media] Input: atmel_mxt: disallow impossible configuration
The newnly added debug mode for the atmel_mxt_ts 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/touchscreen/atmel_mxt_ts.o: In function `mxt_vidioc_querycap':
atmel_mxt_ts.c:(.text.mxt_vidioc_querycap+0x10): undefined reference to `video_devdata'
drivers/input/touchscreen/atmel_mxt_ts.o: In function `mxt_buffer_queue':
atmel_mxt_ts.c:(.text.mxt_buffer_queue+0x20): undefined reference to `vb2_plane_vaddr'
atmel_mxt_ts.c:(.text.mxt_buffer_queue+0x164): undefined reference to `vb2_buffer_done'
drivers/input/touchscreen/atmel_mxt_ts.o: In function `mxt_free_object_table':
atmel_mxt_ts.c:(.text.mxt_free_object_table+0x18): undefined reference to `video_unregister_device'
atmel_mxt_ts.c:(.text.mxt_free_object_table+0x20): undefined reference to `v4l2_device_unregister'

The best workaround I could come up with is to disallow the debug
mode unless it's actually possible to call it.

instead of just the bustype.

This allows for the use of the product variable to set the input_dev->name
variable according to the type of touchscreen used. Note that when we
introduced support for TSC2004 we started calling everything TSC200X, so
let's keep this quirk.

36c0f8b32c [media] vb2: replace void *alloc_ctxs by struct device *alloc_devs
Make this a proper typed array. Drop the old allocate context code since
that is no longer used.

Note that the memops functions now get a struct device pointer instead of
the struct device ** that was there initially (actually a void pointer to
a struct containing only a struct device pointer).

This code is now a lot cleaner.

We should not be ignoring -EPROBE_DEFER reported by
devm_gpiod_get_optional(), but report it as any other error to the upper
layers. While we are at it simplify check for the presence of reset GPIO
and instead of using IS_ERR_OR_NULL just use boolean.

Also do not return -ENOMEM from suspend handler when the device in
bootloader mode as that does not make sense and switch to -EBUSY instead.

72fb4765ac Input: surface3_spi - add surface pen support for Surface 3
This change creates a second input device which will handle input from
a Surface Pen. The Surface Pen supplies a different packet header than
touch events, so it is simple to handle one or the other.

This patch handles both the newer Surface Pen with one button, and the
older variant with a second button to switch to Eraser mode.

4feacbc24e Input: add new driver for the Surface 3
This is a basic driver for the Surface 3. I am not so sure it will work
with any firmwares as most values are encoded, but given that I only have
access to my current device with its firmware and I don't have the
datasheet, it should be OK for now.

The Surface Pen is not supported (if it is supposed to be). I'll work on
this when I get one.
