[PATCHES] assorted debugfs stuff

[Al Viro <viro@zeniv.linux.org.uk>]

	A bit more of debugfs work; that stuff sits in
git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs.git #work.debugfs
Individual patches in followups.  Please, review.

Several removals of pointless debugfs_file_{get,put}():
      zynqmp: don't bother with debugfs_file_{get,put}() in proxied fops
      hfi1: get rid of redundant debugfs_file_{get,put}()
      regmap: get rid of redundant debugfs_file_{get,put}()
      resctrl: get rid of pointless debugfs_file_{get,put}()
Getting rid of the last remnants of debugfs_real_fops():
      vmscan: don't bother with debugfs_real_fops()
      netronome: don't bother with debugfs_real_fops()
      debugfs: split short and full proxy wrappers, kill debugfs_real_fops()

Bogosities in drivers/thermal/testing:
      fix tt_command_write():
1) unbalanced debugfs_file_get().  Not needed in the first place -
file_operations are accessed only via debugfs_create_file(), so
debugfs wrappers will take care of that itself.
2) kmalloc() for a buffer used only for duration of a function is not
a problem, but for a buffer no longer than 16 bytes?
3) strstr() is for finding substrings; for finding a character there's
strchr().

debugfs_get_aux() stuff:
      debugfs_get_aux(): allow storing non-const void *
      blk-mq-debugfs: use debugfs_aux_data()
      lpfc: don't use file->f_path.dentry for comparisons
If you want a home-grown switch, at least use enum for selector...
