Just continue initializing clocks if there's an error on one of them. This is useful if there's a mistake in the inittable, because the system could hang if clk_disable_unused() disables some of the critical clocks in this table.

Perhaps rather than silently ignoring, should this at least print out an error? I'd even go as far as make it a full-blown WARN to make sure people notice and this gets fixed early.
