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) Johan Hovold (8): USB: cdc-acm: fix double free on probe failure USB: cdc-acm: fix use-after-free after probe failure USB: cdc-acm: drop redundant driver-data assignment USB: cdc-acm: drop redundant driver-data reset USB: cdc-acm: clean up probe error labels USB: cdc-acm: use negation for NULL checks USB: cdc-acm: always claim data interface USB: cdc-acm: do not log successful probe on later errors drivers/usb/class/cdc-acm.c | 65 +++++++++++++++++++------------------ 1 file changed, 33 insertions(+), 32 deletions(-) -- 2.26.3
