Look at the uses of DEBUGFS_READONLY_FILE and
see if they are consistent before and after.

 DEBUGFS_READONLY_FILE(rts_threshold, 20, "%d",
-                     wiphy->rts_threshold)
+                     wiphy->rts_threshold);
 DEBUGFS_READONLY_FILE(fragmentation_threshold, 20, "%d",
                      wiphy->frag_threshold);
 DEBUGFS_READONLY_FILE(short_retry_limit, 20, "%d",
-                     wiphy->retry_short)
+                     wiphy->retry_short);
 DEBUGFS_READONLY_FILE(long_retry_limit, 20, "%d",
                      wiphy->retry_long);
