From 2243acd50ac4026e93ac4f024109be6dbd7f9098 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Sun, 2 Apr 2023 19:58:49 +0200 Subject: driver core: class: remove struct class_interface * from callbacks The add_dev and remove_dev callbacks in struct class_interface currently pass in a pointer back to the class_interface structure that is calling them, but none of the callback implementations actually use this pointer as it is pointless (the structure is known, the driver passed it in in the first place if it is really needed again.) So clean this up and just remove the pointer from the callbacks and fix up all callback functions. Cc: Jean Delvare Cc: Guenter Roeck Cc: "David S.
