OMAP clockdomain: if no autodeps exist, don't try to add or remove them
_clkdm_add_autodeps() and _clkdm_del_autodeps() will attempt to dereference a NULL pointer if no autodeps were supplied to clkdm_init(). Based on a patch from Roel Kluin <roel.kluin@gmail.com> - thanks Roel. Signed-off-by: Paul Walmsley <paul@pwsan.com> Cc: Roel Kluin <roel.kluin@gmail.com>
