From: Stephen Kitt Date: Fri, 15 Apr 2022 16:06:09 +0000 (+0200) Subject: ASoC: max980*: use i2c_match_id and simple i2c probe X-Git-Tag: v6.6.17~6759^2~68^2~95^2~3 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=4ac8ebb6cc28cbd99e10d7a4772be1c4da5af130;p=platform%2Fkernel%2Flinux-rpi.git ASoC: max980*: use i2c_match_id and simple i2c probe As part of the ongoing i2c transition to the simple probe ("probe_new"), this patch uses i2c_match_id to retrieve the driver_data for the probed device. The id parameter is thus no longer necessary and the simple probe can be used instead. In the context of an i2c probe, i2c_match_id with the module id table and the probed client never returns null, so removing the null check on the i2c_device_id pointer is safe. The i2c id tables are moved up before the probe function, as suggested by Wolfram Sang.
