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.
