Just a maintainer update and some simple cleanups of the iop-adma
driver.

Thanks,
Dan

    iop-adma: fixup some kzalloc/memset confusions
    
    1) Remove an explicit memset(.., 0, ...) to a variable allocated with
    kzalloc (i.e. 'dest').
    
    2) Allocate 'src' with kmalloc instead of kzalloc as all elements of the
    'src' buffer are initialized in a 'for(...)' loop just after.
    
    3) remove useless 'sizeof(u8)', which always returns 1, when computing the
    size of the memory to be allocated.
