i2c: Make i2c_del_driver a void function
Make i2c_del_driver a void function, like all other driver removal functions. It always returned 0 even when errors occured, and nobody ever actually checked the return value anyway. And we cannot fail a module removal anyway. Signed-off-by: Jean Delvare <khali@linux-fr.org>
