From b912c6564c2973ce0cd24f6d5094f36528eb8eae Mon Sep 17 00:00:00 2001 From: Brian Masney Date: Sat, 12 Nov 2016 13:19:38 -0500 Subject: [PATCH] staging: iio: tsl2583: remove unnecessary memset call The entries in the lux table (als_device_lux) can be updated via sysfs through the function in_illuminance_lux_table_store(). The last row in the table must be terminated with values that are zero. The sysfs code already ensures that the last row is all zeros. The call to memset to clear out the table is not needed so this patch removes the unnecessary call.
