Linus Torvalds d6a326d694 tracing: Remove second argument of __assign_str() 
The __assign_str() macro logic of the TRACE_EVENT() macro was optimized so
 that it no longer needs the second argument. The __assign_str() is always
 matched with __string() field that takes a field name and the source for
 that field:
 
   __string(field, source)
 
 The TRACE_EVENT() macro logic will save off the source value and then use
 that value to copy into the ring buffer via the __assign_str(). Before
 commit c1fa617cae ("tracing: Rework __assign_str() and __string() to not
 duplicate getting the string"), the __assign_str() needed the second
 argument which would perform the same logic as the __string() source
 parameter did. Not only would this add overhead, but it was error prone as
 if the __assign_str() source produced something different, it may not have
 allocated enough for the string in the ring buffer (as the __string()
 source was used to determine how much to allocate)
 
 Now that the __assign_str() just uses the same string that was used in
 __string() it no longer needs the source parameter. It can now be removed.
