Subject[PATCH] cifs: fix checkpatch warnings and normalize strings
Date
Fix checkpatch warnings/errors in smb2ops.c except "LONG_LINE". Add missing
linebreaks, indentings, __func__. Remove void-returns, unneeded braces.

Add SPDX License Header.

Add missing "\n" and capitalize first letter in some cifs_dbg() strings.
