Sebastian Reichel 5165da5923 i2c: i2c-tiny-usb: fix buffer not being DMA capable ... Since v4.9 i2c-tiny-usb generates the below call trace and longer works, since it can't communicate with the USB device. The reason is, that since v4.9 the USB stack checks, that the buffer it should transfer is DMA capable. This was a requirement since v2.2 days, but it usually worked nevertheless.
