[PATCH v2 0/8] USB: cdc-acm: probe fixes

From: Johan Hovold
Date: Mon Mar 22 2021 - 11:54:19 EST


This series fixes a couple of bugs in the probe errors paths and does
some clean up in preparation for adding the missing error handling when
claiming the data interface.

The first two should probably go into 5.12-rc, while the rest could be
held off for 5.13 if preferred.

Johan


Changes in v2
- clarify that the driver already had a check for a bound data
interface and remove the now redundant check (Oliver) (7/8)
- add Oliver's ack to patches 1 through 6
- add new to avoid logging a successful probe message on late errors
(8/8)
