Subject: software node: fix wrong node passed to find nargs_prop
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=c5fc5ba8b6b7bebc05e45036a33405b4c5036c2f;p=linux.git

software node: fix wrong node passed to find nargs_prop

nargs_prop refers to a property located in the reference that is found
within the nargs property. Use the correct reference node in call to
property_entry_read_int_array() to retrieve the correct nargs value.
