From 374de1642ee4322cc4d6aa1d2679378b8547c368 Mon Sep 17 00:00:00 2001 From: Lee Jones Date: Wed, 13 Aug 2014 11:27:34 +0100 Subject: [PATCH] iio: sensors-core: st: Check st_sensors_set_drdy_int_pin()'s return value Value from st_sensors_set_drdy_int_pin() is assigned to err here, but that stored value is not used before it is overwritten. To fix this we're enforcing a check on st_sensors_set_drdy_int_pin()'s return value and if it's an error, we're returning right away.
