Hi all,

After merging the mlx5-next tree, today's linux-next build (x86_64
allmodconfig) produced this warning:

In file included from include/linux/printk.h:331,
from include/linux/kernel.h:15,
from drivers/net/ethernet/mellanox/mlx5/core/mr.c:33:
drivers/net/ethernet/mellanox/mlx5/core/mr.c: In function 'mlx5_core_create_mkey':
include/linux/dynamic_debug.h:157:25: warning: 'key' may be used uninitialized in this function [-Wmaybe-uninitialized]
157 | _dynamic_func_call(fmt,__dynamic_dev_dbg, \
| ^~~~~~~~~~~~~~~~~
drivers/net/ethernet/mellanox/mlx5/core/mr.c:47:5: note: 'key' was declared here
47 | u8 key;
| ^~~

Probably introduced by commit

fc6a9f86f08a ("{IB,net}/mlx5: Assign mkey variant in mlx5_ib only")
