Jan Luebbe 0ecace04a3 ARM: 8892/1: EDAC: Add missing debugfs_create_x32 wrapper
We already have wrappers for x8 and x16, so add the missing x32 one.

Greg Kroah-Hartman 40d7962434 EDAC: Make edac_debugfs_create_x*() return void
The return values of edac_debugfs_create_x16() and
edac_debugfs_create_x8() are never checked (as they don't need to be),
so no need to have them return anything, just make the functions return
void instead.

This is done with the goal of being able to change the debugfs_create_x*
functions to also not return a value.

Thomas Gleixner 457c899653 treewide: Add SPDX license identifier for missed files
Add SPDX license identifiers to all files which:

 - Have no license information of any form

 - Have EXPORT_.*_SYMBOL_GPL inside which was used in the
   initial scan/conversion to ignore the file

These files fall under the project license, GPL v2 only. The resulting SPDX
license identifier is:

Greg Kroah-Hartman 912ebd99ed EDAC: Do not check return value of debugfs_create() functions
When calling debugfs functions, there is no need to ever check the
return value. The function can work or not, but the code logic should
never do something different based on this.

 [ bp: Make edac_debugfs_init() return void too, while at it. ]

Thor Thayer 9bf4f00567 EDAC: Use edac_debugfs_remove_recursive() in edac_debugfs_exit()
debugfs_remove() is used to remove a file or a directory from the
debugfs filesystem on an EDAC device exit. However edac_debugfs might
not be empty. This is similar to

  30f84a891b ("EDAC: Use edac_debugfs_remove_recursive()")

which changed the EDAC MCI code to use edac_debugfs_remove_recursive().

Tan Xiaojun 30f84a891b EDAC: Use edac_debugfs_remove_recursive()
debugfs_remove() is used to remove a file or a directory from the
debugfs filesystem, but mci->debugfs might not empty.

This can be triggered by the following sequence:

1) Enable CONFIG_EDAC_DEBUG
2) insmod an EDAC module (like i3000_edac or similar)
3) rmmod this module
4) we can see files remaining under <debugfs_mountpoint>/edac/ like
   "fake_inject", for example.

Removing edac_core then, causes a NULL pointer dereference.
