* hte: Fix possible use-after-free in tegra_hte_test_remove()Yang Yingliang2022-05-101-1/+1
| | | | | | | | | | | | | | | del_timer() does not wait until the timer handler finishing. This means that the timer handler may still be running after the driver's remove function has finished, which would result in a use-after-free. Fix it by calling del_timer_sync(), which makes sure the timer handler has finished.
