linux-next/drivers/hid/hid-kye.c
Al Viro 5f60d5f6bb move asm/unaligned.h to linux/unaligned.h 
asm/unaligned.h is always an include of asm-generic/unaligned.h;
might as well move that thing to linux/unaligned.h and include
that - there's nothing arch-specific in that header.

auto-generated by the following:

for i in `git grep -l -w asm/unaligned.h`; do
	sed -i -e "s/asm\/unaligned.h/linux\/unaligned.h/" $i
done
for i in `git grep -l -w asm-generic/unaligned.h`; do
	sed -i -e "s/asm-generic\/unaligned.h/linux\/unaligned.h/" $i
done
git mv include/asm-generic/unaligned.h include/linux/unaligned.h
git mv tools/include/asm-generic/unaligned.h tools/include/linux/unaligned.h
sed -i -e "/unaligned.h/d" include/asm-generic/Kbuild
sed -i -e "s/__ASM_GENERIC/__LINUX/" include/linux/unaligned.h tools/include/linux/unaligned.h

* Though we may achieve a usable descriptor from original vendor-defined one,
* some problems exist:
* - Their Logical Maximum never exceed 32767 (7F FF), though device do report
* values greater than that;
* - Physical Maximums are arbitrarily filled (always equal to Logical
* Maximum);
* - Detail for control buttons are not provided (a vendor-defined Usage Page
* with fixed content).
*
* Thus we use a pre-defined parameter table rather than digging it from
* original descriptor.
*
* We may as well write a fallback routine for unrecognized kye tablet, but it's
* clear kye are unlikely to produce new models in the foreseeable future, so we
* simply enumerate all possible models.
