From: Johan Hovold Date: Mon, 25 Jul 2022 07:58:36 +0000 (+0200) Subject: USB: cdc: add serial-state defines X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=a0a3202b44a9fdf2a1f6330a0d176aee76c8631d;p=linux.git USB: cdc: add serial-state defines Add defines for the serial-state bitmap values from section 6.3.5 SerialState of the CDC specification version 1.1. Note that the bTxCarrier and bRxCarrier bits have been named after their RS-232 signal equivalents DSR and DCD.
