This is my fault and not from reset maintainers as i have my own defconfig. Tested and my mux works now again. Maybe this option should be enabled by default or when the i2c-mux is selected? When moving from specific to a generic aproach (which makes sense) imho it should be mentioned in commit description which option needed instead :) btw. the Authors Email seems not working, got : host nokia-com.mail.protection.outlook.com[52.101.73.24] said: 550 5.4.1 Recipient address rejected: Access denied. or maybe its inbox has a whitelist from which domains he can receive mails and my domain is not added to it. regards Frank
