Ben_Nanonote keyboard driver bug

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?

It would be interesting to see what events are being reported by either evbug module or evtest utility.
