Subject: [PATCH] module: tracking: Extend format string of a seq_printf() call
 in unloaded_tainted_modules_seq_show()

Subject: [PATCH] module: tracking: Extend format string of a seq_printf() call in unloaded_tainted_modules_seq_show()

* Move the specification of a single line break from a seq_puts() call
  into the format string of a previous seq_printf() call.

* Omit an extra call of the function “seq_puts”
  because of this refactoring.

This issue was detected by using the Coccinelle software.
