[PATCH 02/45] USB: serial: fix error message on close in generic driver

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Johan Hovold <jhovold@xxxxxxxxx>

Resubmitting read urb fails with -EPERM if completion handler runs while
urb is being killed on close. This should not be reported as an error.
