[PATCH] usb: typec: tcpm: fix state transition for SNK_WAIT_CAPABILITIES state in run_state_machine()

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

 



From: Amit Sunil Dhamne <amitsd@xxxxxxxxxx>

A subtle error got introduced while manually fixing merge conflict in
tcpm.c for commit 85c4efbe6088 ("Merge v6.12-rc6 into usb-next"). As a
result of this error, the next state is unconditionally set to
SNK_WAIT_CAPABILITIES_TIMEOUT while handling SNK_WAIT_CAPABILITIES state
in run_state_machine(...).

Fix this by setting new state of TCPM state machine to `upcoming_state`
(that is set to different values based on conditions).
