From 3cc36cabc669fffa7f04931e3dd25dc47314ec06 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Nuno=20S=C3=A1?= Date: Tue, 4 Oct 2022 15:49:05 +0200 Subject: iio: gyro: itg3200_core: do not use internal iio_dev lock MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The iio_device lock is only meant for internal use. Hence define a device local lock to protect against concurrent accesses. While at it, properly include "mutex.h" for mutex related APIs.
