- Move event bits setup code into a separate function,
  fsp_set_input_params(), so that we can perform hardware-specific settings
  in the future;
- Take hardware version information into account when activating

- Remove button information from boot message as it's somewhat confusing
  and is only for internal processing. While there, also move button
  retrieval code to be a part of protocol activation process.

Some of buttons, like power-on key or onkey, may only generate interrupts
when pressed and not actually be mapped as gpio in the system. Allow
setting gpio to invalid value and specify IRQ instead to support such
keys. The debounce timer is used not to debounce but to ignore new IRQs
coming while button is kept pressed.

Several fixes based on customer feedback:

* WHO_AM_I value has changed since preliminary parts used for initial
  testing;

* Output of le16_to_cpu must be saved to memory before shifting to
  preserve sign;

* Initial data rate was not extracted from data control register init.
  This was causing the initial data rate to be set to maximum until
  it was changed. To fix this problem, it made more sense to specify
  initial data rate and extract the register mask from that.

tries to reference not yet allocated input device.

Also it makes sense to store relative IRQ numbers in max8925_onkey_info

called more often than probe and remove.

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".
Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

.. and also use it in lookup_one_len() rather than open-coding it.

There aren't any performance-critical users, so inlining it is silly.
But it wouldn't matter if it wasn't for the fact that the word-at-a-time
dentry name patches want to conditionally replace the function, and
uninlining it sets the stage for that.

So again, this is a preparatory patch that doesn't change any semantics,
and only prepares for a much cleaner and testable word-at-a-time dentry
name accessor patch.
