From 4a5b45383ca371e123ba103d34d4b3b87616245c Mon Sep 17 00:00:00 2001 From: Christophe JAILLET Date: Sun, 8 Apr 2018 21:44:01 +0200 Subject: [PATCH] iio: sca3000: Fix an error handling path in 'sca3000_probe()' Use 'devm_iio_kfifo_allocate()' instead of 'iio_kfifo_allocate()' in order to simplify code and avoid a memory leak in an error path in 'sca3000_probe()'. A call to 'sca3000_unconfigure_ring()' was missing. Sent via the next merge window as unimportant bug and there are other patches dependent on it.
