+Subject: [PATCH] rescan-scsi-bus: Do not use printf for summary
+
+A string containing escape sequences can only be supplied
+to `printf` as the first argument. As there's no format involved
+in the summary string, just use `echo -e` to process the escaped
+sequences.
+
+Fixes the following phenomenon:
+
+1 new or changed device(s) found.
+\t[1:0:0:0]\n0 remapped or resized device(s) found.
+0 device(s) removed.
