From ceb1edc2a0a52b6f4285fbfc8f29a42b6109e52d Mon Sep 17 00:00:00 2001 From: Christian Gromm Date: Tue, 8 May 2018 11:44:51 +0200 Subject: [PATCH] staging: most: i2c: prevent division by zero This prevents division by zero scan_rate. The zero scan_rate does not need any special action as it actually means "never poll again".
