Subject: regression in iwlwifi: page fault in iwl_dbg_tlv_alloc_region()
 (commit ba8f6f4ae254)

FYI, there is a regression in iwlwifi driver caused by commit
ba8f6f4ae254 ("iwlwifi: dbg: add dumping special device memory")
reported at

  https://bugzilla.kernel.org/show_bug.cgi?id=210733
  https://bugzilla.suse.com/show_bug.cgi?id=1180344

The problem seems to be an attempt to write terminating null character
into a string which may be read only. There is also a proposed fix.
