Subject: tools: efivar.py without arguments
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=4f6ec7754b1342ae9f9df4524fa9fa45299f3d68;p=u-boot.git

tools: efivar.py without arguments

When tools: efivar.py is called without arguments an error occurs:

Traceback (most recent call last):
  File "tools/efivar.py", line 380, in <module>
    main()
  File "tools/efivar.py", line 360, in main
    args.func(args)
AttributeError: 'Namespace' object has no attribute 'func'

Show the online help if the arguments do not specify a function.
