[PATCH 5.15 068/117] thunderbolt: Use correct function to calculate maximum USB3 link rate

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

 



From: Mika Westerberg <mika.westerberg@xxxxxxxxxxxxxxx>

commit e8ff07fb33026c5c1bb5b81293496faba5d68059 upstream.

We need to take minimum of both sides of the USB3 link into consideration,
not just the downstream port. Fix this by calling tb_usb3_max_link_rate()
instead.

Fixes: 0bd680cd900c ("thunderbolt: Add USB3 bandwidth management")
