[v2,0/3] staging: gigaset: fix crashes on probe

Message

Johan Hovold Dec. 2, 2019, 8:56 a.m. UTC

Syzbot has been reporting a GPF on probe in the gigaset ISDN driver,
which have since been moved to staging.

The first patch fixes that issue, and the next one fixes a second crash
found during testing.

The third patch addresses a benign warning in USB core which syzbot is
bound to report once the crashes have been fixed.

Changes in v2
 - use usb_endpoint_is_bulk_out() and friends in patch 3/3, and drop
   patch 4/4 which only renamed an identifier.


Johan Hovold (3):
  staging: gigaset: fix general protection fault on probe
  staging: gigaset: fix illegal free on probe errors
  staging: gigaset: add endpoint-type sanity check
