Subject: cmd/command.c: relax length check in cmd_get_data_size()
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=92fa22a1bb1e77e05b20e7caa854101bb15ccfef;p=u-boot.git

cmd/command.c: relax length check in cmd_get_data_size()

Just check that the length is at least 2. This allows passing strings
like ".b", which can be convenient when constructing
tests (i.e. parametrizing the suffix used).
