Merge tag 'iio-for-4.15a' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next

Jonathan writes: Round one of new device support, features and cleanup for IIO in the 4.15 cycle. Note there is a misc driver drop in here given we have support in IIO and the feeling is no one will care. A large part of this series is a boiler plate removal series avoiding the need to explicitly provide THIS_MODULE in various locations. It's very dull but touches all drivers. New device support * ad5446 - add ids to support compatible parts DAC081S101, DAC101S101, DAC121S101. - add the dac7512 id and drop the misc driver as feeling is no one is using it (was introduced for a board that is long obsolete) * mt6577 - add bindings for mt2712 which is fully compatible with other supported parts. * st_pressure - add support for LPS33HW and LPS35HW with bindings (ids mostly). New features * ccs811 - Add support for the data ready trigger. * mma8452 - remove artifical restriction on supporting multiple event types at the same time. * tcs3472 - support out of threshold events Core and tree wide cleanup * Use macro magic to remove the need to provide THIS_MODULE as part of struct iio_info or struct iio_trigger_ops. This is similar to work done in a number of other subsystems (e.g. i2c, spi). All drivers are fixed and then the fields in these structures are removed. This will cause build failures for out of tree drivers and any new drivers that cross with this work going into the kernel. Note mostly done with a coccinelle patch, included in the series on the mailing list but not merged as the fields no longer exist in the structures so the any hold outs will cause a build failure. Cleanups * ads1015 - avoid writing config register when it doesn't change. - add 10% to conversion wait time as it seems it is sometimes a little small. * ade7753 - replace use of core mlock with a local lock. This is part of a long term effort to make the use of mlock opaque and single purpose. * ade7759 - expand the use of buf_lock to cover previous mlock cases. This is a slightly nicer solution to the same issue as in ade7753. * cros_ec - drop an unused variable * inv_mpu6050 - add a missing break in a switch for consistency - not actual bug, - make some local arrays static to save on object code size. * max5481 - drop manual setting of the spi module owner as handled by the spi core. * max5487 - drop manual setting of the spi module owner as handled by the spi core. * max9611 - drop explicit setting of the i2c module owner as handled by the i2c core. * mcp320x - speed up reads on single channel devices, - drop unused of_device_id data elements, - document the struct mcp320x, - improve binding docs to reflect restrictions on spi setup and to make it explicit that the reference regulator is needed. * mma8452 - symbolic to octal permissions, - unsigned to unsigned int. * st_lsm6dsx - avoid setting odr values multiple times, - drop config of LIR as it is only ever set to the existing defaults, - drop rounding configuration as it only ever matches the defaults. * ti-ads8688 - drop manual setting of the spi module owner as handled by the spi core. * tsl2x7x - constify the i2c_device_id, - cleanup limit checks to avoid static checker warnings (and generally have nicer code).
