David Wei 4e3401aa6e tools: ynl-gen: validate 0 len strings from kernel 
[ Upstream commit 4720f9707c ]

Strings from the kernel are guaranteed to be null terminated and
ynl_attr_validate() checks for this. But it doesn't check if the string
has a len of 0, which would cause problems when trying to access
data[len - 1]. Fix this by checking that len is positive.
