Subject[PATCH] Input: omap4-keypad - don't leak in omap4_keypad_probe()
If omap4_keypad_parse_dt() does not return 0 (zero) in
omap4_keypad_probe() we will leak the memory we allocated for
'keypad_data' with kzalloc() when we return and the variable goes out
of scope.
Fix the leak by jumping to the 'err_free_keypad' label where we
properly free the allocated memory, instead of returning directly.
