Subject: [PATCH] net: usb: sr9700: fix incorrect command used to write single register
Date: Sat, 20 Dec 2025 23:27:32 -0800	[thread overview]
Message-ID: <20251221072732.41426-1-enelsonmoore@gmail.com> (raw)

This fixes the device failing to initialize with "error reading MAC
address" for me, probably because the incorrect write to
NCR_RST is not actually resetting the device.

Fixes: c9b37458e95629b1d1171457afdcc1bf1eb7881d ("USB2NET : SR9700 : One chip USB 1.1 USB2NET SR9700Device Driver Support")
