| | | | | | | | | | | | | | | | | | | Don't use create_proc_read_entry() as that is deprecated, but rather use proc_create_data() and seq_file instead. Whilst we're at it, reduce the number of show functions where we can share them. Question: Do any of the registers read by proc_get_registers() have side effects upon reading? If so, locking will be required.

* rtl8192u: Don't use create_proc_read_entry()David Howells2013-04-29
| | | | | | | | | | | | | | | | | | | | | | Don't use create_proc_read_entry() as that is deprecated, but rather use proc_create_data() and seq_file instead. Whilst we're at it, reduce the number of show functions where we can share them. Note: proc_get_stats_ap() should probably use seq_file iteration rather than list_for_each_entry(). Further note: There appears to be a lot of locking missing in this file to defend against concurrent access by the driver doing normal operations. Notably, ieee->network_list traversal and RWCAM/RCAMO command/response access. Further, do any of the registers read have side effects upon reading?
