From 96e5d1b1e69097cb89f8002770cccf464c0dfa1c Mon Sep 17 00:00:00 2001 From: Johan Hovold Date: Mon, 10 Nov 2025 12:12:10 +0100 Subject: [PATCH] USB: serial: ftdi_sio: enable NDI speed hack consistently The original submission adding support for NDI EMGUIDE Gemini enabled the existing NDI speed hack which remaps the 19200 line speed to 1.2 Mbps, but this silently fell out during resubmission. Enable the speed hack also for the new NDI product for consistency. This will also allow for cleaning up the implementation without resorting to overengineering.
