Subject: [PATCH v3 0/4] EDAC/mc: Fixes for mci device removal

This series is a split of

 [v2] EDAC/mc: Fix use-after-free and memleaks during device removal
 https://lore.kernel.org/patchwork/patch/1190002/

in smaller patches to better handle stable backports.

Patch #1 helps to ease backports of patch #2 to 5.3 and earlier
kernels, see patch descriptions of both for details.

Patch #2 is the smallest possible fix to address use-after-free and
memleak issues aimed for backports.

Patch #3 is another small patch that is split off for stable. This
fixes code already commited to stable trees.

Patch #4 is the all remaining code containing the rework of the mci
device removal. Resulting code is the same as in v2 except for the
changes outlined for v3:

v3:
 * split patch into smaller pieces to ease backports,
 * removed edac_remove_sysfs_mci_device() in edac_mc_free(), at this
   point the mci device is always unregistered

Robert Richter (4):
  Revert parts of "EDAC/mc_sysfs: Make debug messages consistent"
  EDAC/mc: Fix use-after-free and memleaks during device removal
  EDAC/sysfs: Remove csrow objects on errors
  EDAC/mc: Change mci device removal to use put_device()
