Fix for omap1 mailbox driver.
This will enable DSP Gateway again.

I'll work more on mudularization of dsp and mailbox.

Allrifght Rajesh, you should first tell us to which kind of plateform
you're porting Linux to. Actually, "porting linux to OMAP1510" makes
virtually no sense, given that the port is already done and totally
functionnal. Porting Linux to a device using an OMAP processor would,
but you should tell us more about it if you expect an interesting
answer.

Romain

For that matter, seems that 
drivers/input/keyboard/innovator_ps2.c used on Innovator 
1510 is broken:

   CC [M]  drivers/input/keyboard/innovator_ps2.o
drivers/input/keyboard/innovator_ps2.c: In function 
'innovator_kbd_init':
drivers/input/keyboard/innovator_ps2.c:1225: warning: 
implicit declaration of function 'init_input_dev'

WARNING: "init_input_dev" 
[drivers/input/keyboard/innovator_ps2.ko] undefined!

Cheers
