# \[PATCH 7/8\] mwifiex: don't print an error if an optional DT property is missing - From: Javier Martinez Canillas \ - Date: 2016-05-27 14:19:54 - List: netdev - Page: https://ratatoskr.run/netdev/2016/05/4759073 - Thread: https://ratatoskr.run/netdev/2016/05/4759065/t.md ```text The Documentation/devicetree/bindings/net/wireless/marvell-sd8xxx.txt DT binding document say that the "interrupts" property in the child node is optional. So the property being missed shouldn't be treated as an error.
