While moving to devl_ API the patchset removes part of the devlink API functions which mlx5 was the last one to use and so not used by any driver now. The patchset also remove DEVLINK_NL_FLAG_NO_LOCK flag from the callbacks of port_new/port which are called only from mlx5 driver and the already locked by the patchset as parallel paths to the eswitch callbacks using devl_ API functions. This patchset will be followed by another patchset that will remove DEVLINK_NL_FLAG_NO_LOCK flag from devlink reload and devlink health callbacks. Thus we will have all devlink callbacks locked and it will pave the way to remove devlink mutex. =================== Link: https://lore.kernel.org/r/20220711081408.69452-1-saeed@kernel.org Signed-off-by: Paolo Abeni --- bfc54866856ffe2cb82886337afdece7703f2415
