From abaf00ff04625275a40e407fc8da04948ae4f95b Mon Sep 17 00:00:00 2001 From: Oliver Neukum <oneukum@suse.com> Date: Wed, 5 Aug 2020 14:07:09 +0200 Subject: [PATCH] usb: hso: remove bogus check for EINPROGRESS This check an inherent race. It opens a race where an error code has already been set or cleared yet the URB has not been given back. We cannot do such an optimization and must unlink unconditionally.
