Subject: [PATCH 11/28] staging: most: i2c: trace real polling rate
Date: Tue, 8 May 2018 11:44:59 +0200	[thread overview]
Message-ID: <1525772716-15742-12-git-send-email-christian.gromm@microchip.com> (raw)
In-Reply-To: <1525772716-15742-1-git-send-email-christian.gromm@microchip.com>

The real polling rate depends on the CONFIG_HZ and may differ from the
required polling rate.
