From: Xie XiuQi <xiexiuqi@...wei.com>

'make export_report' with CONFIG_MODVERSIONS enabled, but we get this warning
message and empty export-symbol-usage SECTION.

  $ make export_report
  ...

  SECTION 2:
          This section reports export-symbol-usage of in-kernel
  modules. Each module lists the modules, and the symbols from that module that
  it uses.  Each listed symbol reports the number of modules using it

  NOTE: Got 9 CONFIG_MODVERSIONS warnings

The causes of the problem is that the formats of modules.order and .mod.c are
changed, but the modification for export_report.pl is missing. So, fix them.

Xie XiuQi (3):
  scripts/export_report.pl: fix the path suffix of module
  scripts/export_report.pl: use the module name in warning message
  scripts/export_report.pl: fix modversion checking
