Hi 

with Dmitry's help, our keyboard is work.

we use the matrix_keypad.c driver. I found a problem.
for example. the keypad is like this: (part of keypad)  
GPIO    GPIO    GPIO
|       |       |  
a_______w_______u_____GPIO
|	|	|
|_______s_______j_____GPIO
|	|	|
Shift___Alt_____Ctrl__GPIO

first time press [Shift] + [a] it's output [a] not the [A]
second time press [Shift] + [a] it's output [A]. correct.
then all work fine.  but when I release the [Shift]. and press [a]
it's will also output big [A]. but if the midifier and character not 
in same column GPIO. it will work fine. 

other modifier all like this. same GPIO will cause problem.

I should look into the matrix_keypad.c to fix this, right?

Best Regards
