From: JackyChou Date: Fri, 30 Nov 2018 06:31:22 +0000 (+0800) Subject: USB: serial: mos7840: add a product ID for the new product X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=32899682cf457de5c091ee7dbbee34ad9bf2f992;p=openwrt%2Fstaging%2Fblogic.git USB: serial: mos7840: add a product ID for the new product Add a new PID 0x7843 to the driver. Let the new products be able to set up 3 serial ports with the driver. Note that this depends on e8603076f540 ("USB: serial: mos7840: clean up register handling").
