From: Jonathan Cameron Date: Sun, 25 Sep 2022 15:57:18 +0000 (+0100) Subject: iio: imu: inv_icm42600: Move exports to IIO_ICM42600 namespace X-Git-Tag: v6.6.17~5900^2~20^2~93 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=ef5a5ef29c8f70ca640d785b7173101417c78d24;p=platform%2Fkernel%2Flinux-rpi.git iio: imu: inv_icm42600: Move exports to IIO_ICM42600 namespace As these exports are only relevant to core module and users in the bus specific modules, move them out of the main kernel namespace. Includes using EXPORT_NS_GPL_DEV_PM_OPS() and the simplifications that brings by allowing the compiler to remove unused struct dev_pm_ops and callbacks without needing explicit __maybe_unused markings.
