From ea14163d29130649e43bfcad12ef6ef9a956fbe3 Mon Sep 17 00:00:00 2001 From: Alexandru Ardelean Date: Tue, 17 Sep 2019 19:10:23 +0300 Subject: iio: gyro: adis16130: remove mlock usage The use of indio_dev's mlock is discouraged. The driver already defines it's own `bus_lock` in `adis16130_spi_read()`, so using the mlock is redundant. The parts supported by this chip are obsoleted anyway, so for now we just remove mlock as part of a general cleanup, until the driver gets removed.
