From: Eder Zulian <ezulian@xxxxxxxxxx>
commit 3d7b8ea7a8a20a45d019382c4dc6ed79e8bb95cf upstream.
The help text in osnoise top and timerlat top had some minor errors
and omissions. The -d option was missing the 's' (second) abbreviation and
the error message for '-d' used '-D'.
Cc: stable@xxxxxxxxxxxxxxx
Fixes: 1eceb2fc2ca54 ("rtla/osnoise: Add osnoise top mode")
Fixes: a828cd18bc4ad ("rtla: Add timerlat tool and timelart top mode")
