If anyone has any objections, please let me know. ------------------ From: Runyu Xiao [ Upstream commit 30167fadbf87fa901a2fee49c30a5c5a506a43e8 ] tegra_hte_test_remove() releases GPIO descriptors before stopping hte.timer. gpio_timer_cb() accesses hte.gpio_out and rearms the timer, so a callback concurrent with remove can use a released descriptor and rearm after teardown. Shut down the timer before releasing the GPIO descriptors. timer_shutdown_sync() waits for a running callback and prevents it from being rearmed.
