In the Linux kernel, the following vulnerability has been resolved: lan966x: Fix sleeping in atomic context The following warning was seen when we try to connect using ssh to the device. BUG: sleeping function called from invalid context at kernel/locking/mutex.c:575 in_atomic(): 1, irqs_disabled(): 0, non_block: 0, pid: 104, name: dropbear preempt_count: 1, expected: 0 INFO: lockdep is turned off.

Change the mutex with a spinlock.
