[PATCH] use list_for_each_entry() for iteration in Prism 54 driver
Use list_for_each_entry() instead of manual iteration and substitute a list_for_each_safe() loop with list_for_each_entry_safe() Signed-off-by: Matthias Kaehlcke <matthias.kaehlcke@gmail.com> Cc: Christoph Hellwig <hch@lst.de> Acked-by: Luis R.
