+Possible dereference of NULL
+Description of problem:
+There is possible dereference of NULL using macro QEMU_LOCK_GUARD(&q->lock) in:
+1) /block/nvme.c line [326](https://github.com/qemu/qemu/blob/5da72194df36535d773c8bdc951529ecd5e31707/block/nvme.c#L326)
+2) /include/qemu/ratelimit.h line [45](https://github.com/qemu/qemu/blob/5da72194df36535d773c8bdc951529ecd5e31707/include/qemu/ratelimit.h#L45)
+3) /include/qemu/ratelimit.h line [88](https://github.com/qemu/qemu/blob/5da72194df36535d773c8bdc951529ecd5e31707/include/qemu/ratelimit.h#L88)
+
+
+The QEMU_MAKE_LOCKABLE(x) macro provides a special case (line [71](https://github.com/qemu/qemu/blob/5da72194df36535d773c8bdc951529ecd5e31707/include/qemu/lockable.h#L71) of the lockable.h) if NULL gets into it. Then the macro will return NULL, which will get to the input of the qemu_lockable_auto_lock() function, then to the qemu_lockable_lock() function, where NULL dereference will occur (line [95](https://github.com/qemu/qemu/blob/5da72194df36535d773c8bdc951529ecd5e31707/include/qemu/lockable.h#L95)).
+
+It turns out that the NULL case is provided, but not handled properly. I think a NULL check should be added.
