Aligned this struct better.
This patch (and this struct) introduces another section mismatch warning
because it references another struct which is __initdata but the struct
itself is not:

WARNING: vmlinux.o(.data+0x37788): Section mismatch in reference from
the variable keypad_data to the (unknown reference) .init.data:(unknown)
The variable keypad_data references
the (unknown reference) __initdata (unknown)

A quick glance suggests the the right fix is that this struct should
also be __initdata:
Yes , will incorporate the comments and send a patch.
