Merge first round of changes for 3.12 merge window.

SYN_* events are special and not enabled via set_bit() for devices. Hence,
they haven't been really needed, yet. However, user-space can still make
great use of that for int->string debugging helpers or alike.

Also, I haven't seen any reason not to define these, so here they are.

I haven't had time to work on this driver for a long time and
Ferruh has been doing a great job making it more generic,
adding support for new hardware and providing bug fixes.

So, let's make MAINTAINERS reflect reality and add him as the
cyttsp maintainer instead of me.

Also, since Ferruh works for Cypress, we may change the driver
status from Maintained to Supported.

This driver adds support for slidebars found on some Lenovo IdeaPad
laptops (the slidebars work with SlideNav/Desktop Navigator under
Windows).

Fixes: https://bugzilla.kernel.org/show_bug.cgi?id=16004

Registers 'IdeaPad Slidebar' input device and
/sys/devices/platform/ideapad_slidebar/slidebar_mode
for switching slidebar's modes.

Now works on:
IdeaPad Y550, Y550P.

May work on (testing and adding new models is needed):
Ideapad Y560, Y460, Y450, Y650,
and, probably, some others.

The signatures of v3 and v4 packets change depending on the value of a
hardware flag called 'crc_enabled'. The packet type detection must change
accordingly.

This patch also restores a consistency check for v4 packets inadvertently
removed by commit:

9eebed7d
Input: elantech - fix for newer hardware versions (v7)

A note about the naming convention: v3 hardware is associated with IC body
v5 while v4 hardware is associated with IC body v6 and v7. The above commit
refers to IC body v7, not to v7 hardware.

Tested on Samsung NP730U3E (fw = 0x675f05, ICv7, crc_enabled = 1)

Remove unneeded error handling on the result of a call to
platform_get_resource when the value is passed to devm_ioremap_resource.

Move the call to platform_get_resource adjacent to the call to
devm_ioremap_resource to make the connection between them more clear.

follows: (http://coccinelle.lip6.fr/)

* Fix version recognition in elantech_set_properties

  The new hardware reports itself as v7 but the packets'
  structure is unaltered.

* Fix packet type recognition in elantech_packet_check_v4

  The bitmask used for v6 is too wide, only the last three bits of
  the third byte in a packet (packet[3] & 0x03) are actually used to
  distinguish between packet types.
  Starting from v7, additional information (to be interpreted) is
  stored in the remaining bits (packets[3] & 0x1c).
  In addition, the value stored in (packet[0] & 0x0c) is no longer
  a constant but contains additional information yet to be deciphered.
  This change should be backwards compatible with v6 hardware.
