[PATCH] [trivial] drivers/input/joystick/grip_mp.c: ARRAY_SIZE

[Andi Drebes <lists-receive@programmierforen.de>]

This patch replaces an array size calculation in drivers/input/joystick/grip_mp.c
that was done using sizeof with the ARRAY_SIZE macro. To be more specific,
I replaced a variable called seq_len in the function dig_mode_start that stored
the size of the array with ARRAY_SIZE. The variable was referenced only once,
so I think removing it is ok.

Tested by compilation on an i386 box using "allyesconfig".
Diffed against Linus' git-tree.
