Subject: [PATCH 1/4] hid-quirks: Add NO_INIT_REPORTS quirk for Synaptics Touch
Pad V 103S
This touchpad seriously dislikes init reports, not only timeing out, but
also refusing to work after this.

Subject: [PATCH 2/4] elantech: Fix elantech on Gigabyte U2442
The hw_version 3 elantech touchpad on the Gigabyte U2442 does not accept
0x0b as initialization value for r10, this stand-alone version of the driver:
http://planet76.com/drivers/elantech/psmouse-elantech-v6.tar.bz2
Uses 0x03 which does work, so this means not setting bit 3 of r10 which sets:
"Enable Real H/W Resolution In Absolute mode"
Which will result in half the x and y resolution we get with that bit set,
so simply not setting it everywhere is not a solution. We've been unable
to find a way to identifty touchpads where setting the bit will fail, so this
patch uses a dmi based blacklist for this.

EEE PC 1015PX
Without this this EEE PC exports a non working WMI interface, with this it
exports a working "good old" eeepc_laptop interface, fixing brightness control
not working as well as rfkill being stuck in a permanent wireless blocked
state.
This is not an ideal way to fix this, but various attempts to fix this
otherwise have failed, see:
