From 47f82769181fdb755bc86aff881775357383ff68 Mon Sep 17 00:00:00 2001 From: Jiri Slaby Date: Fri, 18 Jun 2021 08:14:36 +0200 Subject: mxser: remove MOXA_HighSpeedOn ioctl 1) The semantics are defined exactly nowhere. 2) The ioctl definition was never exposed to userspace, so noone should actually be reliably using this. 3) It's not even mentioned in any of the mxser utilities. Provided the above, remove this mxser-special ioctl.
