iwlwifi: make tracing use device as identifier
Tracing used the priv pointer as an identifier, which has the problem that we don't have it in all code, and also some people say no pointers should be "leaked" to userspace. Use the device name instead, it is more useful anyway. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com> Signed-off-by: John W.
