[PATCH] iommu/ipmmu-vmsa: Minor cleanups

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Remove the of_match_ptr() which was supposed to have gone long ago, but
managed to got lost in a fix-squashing mishap. On a similar theme, we
may as well also modernise the PM ops to get rid of the clunky #ifdefs,
and modernise the resource mapping to keep the checkpatch brigade happy.
