[PATCH 5.10 195/563] software node: fix wrong node passed to find nargs_prop

[Greg Kroah-Hartman]

From: Clément Léger <clement.leger@xxxxxxxxxxx>

[ Upstream commit c5fc5ba8b6b7bebc05e45036a33405b4c5036c2f ]

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.

Fixes: b06184acf751 ("software node: Add software_node_get_reference_args()")
