Title
Bluetooth: btnxpuart: Fix random crash seen while removing driver
Summary
In the Linux kernel, the following vulnerability has been resolved: Bluetooth: btnxpuart: Fix random crash seen while removing driver This fixes the random kernel crash seen while removing the driver, when running the load/unload test over multiple iterations. 1) modprobe btnxpuart 2) hciconfig hci0 reset 3) hciconfig (check hci0 interface up with valid BD address) 4) modprobe -r btnxpuart Repeat steps 1 to 4 The ps_wakeup() call in btnxpuart_close() schedules the psdata->work(), which gets scheduled after module is removed, causing a kernel crash. This hidden issue got highlighted after enabling Power Save by default in 4183a7be7700 (Bluetooth: btnxpuart: Enable Power Save feature on startup) The new ps_cleanup() deasserts UART break immediately while closing serdev device, cancels any scheduled ps_work and destroys the ps_lock mutex.
