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

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.
