Pull PNP updates from Rafael Wysocki:
 "These get rid of unnecessary local variables and function, reduce code
  duplication and clean up message printing.

  Specifics:

   - Remove unnecessary local variables from isapnp_proc_attach_device()
     (Anupama K Patil).

   - Make the callers of pnp_alloc() use kzalloc() directly and drop the
     former (Heiner Kallweit).

   - Make two pieces of code use dev_dbg() instead of dev_printk() with
     the KERN_DEBUG message level (Heiner Kallweit).

   - Use DEVICE_ATTR_RO() instead of full DEVICE_ATTR() in some places
     in card.c (Zhen Lei).

   - Use list_for_each_entry() instead of list_for_each() in
     insert_device() (Zou Wei)"
