I wrote a quick test program to check that this patch doesn't change
what key we generate for any particular qcode (you can find the test
program at http://people.linaro.org/~peter.maydell/adb-test.c),
but it shows up a handful of changes:

qcode 5 pckey 0x64 oldadb 0x0 newadb 0x7c
qcode 82 pckey 0x54 oldadb 0x0 newadb 0x69
qcode 93 pckey 0x56 oldadb 0xa newadb 0x0
qcode 96 pckey 0xb7 oldadb 0x0 newadb 0x69
qcode 118 pckey 0x0 oldadb 0x0 newadb 0x72
qcode 120 pckey 0xdc oldadb 0x7e newadb 0x37
qcode 122 pckey 0x0 oldadb 0x0 newadb 0x71
qcode 125 pckey 0x0 oldadb 0x0 newadb 0x51

That's Q_KEY_CODE_ALTGR, Q_KEY_CODE_SYSRQ,
Q_KEY_CODE_LESS, Q_KEY_CODE_PRINT, Q_KEY_CODE_HELP,
Q_KEY_CODE_META_R, Q_KEY_CODE_PAUSE, Q_KEY_CODE_KP_EQUALS.

I suspect these are all bugfixes to the layout, but they should
be done in a separate patch, so that this patch doesn't change
behaviour at all.

If you fix the qcode_to_adb_keycode[] array so that it gives the
same results for those entries as the existing code then this
patch is good.

thanks
