The current implementation of elan_i2c is known to not support those
2 laptops.
A proper fix is to tweak both elantech and elan_i2c to transmit the
correct information from PS/2, which would make a bad candidate for
stable.
So to give us some time for fixing the root of the problem, disable
elan_i2c for the devices we know are not behaving properly.

With PM enabled, I noticed that pressing a key on the droid4 keyboard will
block deeper idle states for the SoC. Let's fix this by using IRQF_ONESHOT
and stop constantly toggling the device OMAP4_KBD_IRQENABLE register as
suggested by Dmitry Torokhov <dmitry.torokhov@gmail.com>.
From the hardware point of view, looks like we need to manage the registers
for OMAP4_KBD_IRQENABLE and OMAP4_KBD_WAKEUPENABLE together to avoid
blocking deeper SoC idle states. And with toggling of OMAP4_KBD_IRQENABLE
register now gone with IRQF_ONESHOT, also the SoC idle state problem is
gone during runtime. We still also need to clear OMAP4_KBD_WAKEUPENABLE in
omap4_keypad_close() though to pair it with omap4_keypad_open() to prevent
blocking deeper SoC idle states after rmmod omap4-keypad.

This updated version is using macros, and also fixes the use of the

use the known good Android kernel values of 3 and 6 instead of 2 and 6

The cros_ec_keyb_bs array lists buttons and switches together, expecting
that its users will match the appropriate type and bit fields. But
cros_ec_keyb_register_bs() only checks the 'bit' field, which causes
misreported input capabilities in some cases. For example, tablets
(e.g., Scarlet -- a.k.a. Acer Chromebook Tab 10) were reporting a SW_LID
capability, because EC_MKBP_POWER_BUTTON and EC_MKBP_LID_OPEN happen to
share the same bit.
(This has comedic effect on a tablet, in which a power-management daemon
then thinks this "lid" is closed, and so puts the system to sleep as
soon as it boots!)
To fix this, check both the 'ev_type' and 'bit' fields before reporting
the capability.
Tested with a lid (Kevin / Samsung Chromebook Plus) and without a lid
(Scarlet / Acer Chromebook Tab 10).
This error got introduced when porting the feature from the downstream
Chromium OS kernel to be upstreamed.

"of_get_named_gpio()" returns a negative error value if it fails
and drivers should check for this. This missing check was now
added to the matrix_keypad driver.
In my case "of_get_named_gpio()" returned -EPROBE_DEFER because
the referenced GPIOs belong to an I/O expander, which was not yet
probed at the point in time when the matrix_keypad driver was
loading. Because the driver did not check for errors from the
"of_get_named_gpio()" routine, it was assuming that "-EPROBE_DEFER"
is actually a GPIO number and continued as usual, which led to further
errors like this later on:
WARNING: CPU: 3 PID: 167 at drivers/gpio/gpiolib.c:114
gpio_to_desc+0xc8/0xd0
invalid GPIO -517
Note that the "GPIO number" -517 in the error message above is
actually "-EPROBE_DEFER".
As part of the patch a misleading error message "no platform data defined"
was also removed. This does not lead to information loss because the other
error paths in matrix_keypad_parse_dt() already print an error.

Pull XArray conversion from Matthew Wilcox:
"The XArray provides an improved interface to the radix tree data
structure, providing locking as part of the API, specifying GFP flags
at allocation time, eliminating preloading, less re-walking the tree,
more efficient iterations and not exposing RCU-protected pointers to
its users.
This patch set
1. Introduces the XArray implementation
2. Converts the pagecache to use it
3. Converts memremap to use it
The page cache is the most complex and important user of the radix
tree, so converting it was most important. Converting the memremap
code removes the only other user of the multiorder code, which allows
us to remove the radix tree code that supported it.
I have 40+ followup patches to convert many other users of the radix
tree over to the XArray, but I'd like to get this part in first. The
other conversions haven't been in linux-next and aren't suitable for
applying yet, but you can see them in the xarray-conv branch if you're

take compat TIOC[SG]SERIAL treatment into tty_compat_ioctl()
synclink: reduce pointless checks in ->ioctl()
complete ->[sg]et_serial() switchover
...
A small update with a couple of new APIs that are useful for some small
sets of devices:
- Split up the single_rw flagging to map read and write separately as
some devices support bulk operations for only read or only write.
- Add a write version of the noinc API.
- Clean up the code for LOG_DEVICE a bit.

synaptics_detect() does not check whether sending commands to the
device succeeds and instead relies on getting unique data from the
device. Let's make sure we seed entire buffer with zeroes to make sure
we will not use garbage on stack that just happen to be 0x47.

In preparation to enabling -Wimplicit-fallthrough, mark switch cases
where we are expecting to fall through.
Notice that in this particular case, I placed the "fall through"
part at the beginning of the code comment, which is what GCC is
expecting to find.
