This is an incremental patch updating to the revised bindings for
matrix keyboards.
This includes an optional "linux,fn-keymap" binding that is not yet
implemented, that will be used to specify the Fn-key modifier layout
if needed.

Change 0 to NULL in the last argument of request_irq, since the argument
should have pointer type and so that the last argument of request_irq
syntactically matches the second argument of the later call to free_irq.

Input device must be allocated (but not necessarily registered) before
requesting IRQs, otherwise there is a chance that IRQ handler fires and
tries to reference not yet allocated input device.
Also it makes sense to store relative IRQ numbers in max8925_onkey_info
structure as they are needed in suspend/resume which we expect to be
called more often than probe and remove.

This fixes reference-before-check problem; there is no reason to check
if caller passed NULL dev or bus_ops as it is done only by bus-specific
drivers which already do the right thing.

The Data Modul TP 72037 EasyTouch controller is derived from EGALAX
controller and is capable of detecting dual contacts. Packets can be 5
bytes or 10 bytes long, depending whether one or two contacts are
detected. Format is same as EGALAX touch controller, but with x and y
coordinates inverted.

This patch adds support for TI's touchscreen
controller for a 4/5/8 wire resistive panel
that is directly fed to the ADC.
This touchscreen controller will be part of
AM335x TI SoC. The TRM can be found at:

The code in link_path_walk() that finds out the length and the hash of
the next path component is some of the hottest code in the kernel. And
I have a version of it that does things at the full width of the CPU
wordsize at a time, but that means that we *really* want to split it up
into a separate helper function.
So this re-organizes the code a bit and splits the hashing part into a
helper function called "hash_name()". It returns the length of the
pathname component, while at the same time computing and writing the
hash to the appropriate location.
The code generation is slightly changed by this patch, but generally for
the better - and the added abstraction actually makes the code easier to
read too. And the new interface is well suited for replacing just the
"hash_name()" function with alternative implementations.

It did some odd things for unclear reasons. As this is one of the
functions that gets changed when doing word-at-a-time compares, this is
yet another of the "don't change any semantics, but clean things up so
that subsequent patches don't get obscured by the cleanups".
