From 5f6333bd6ed3c855c725ab389eeed8bf7c198798 Mon Sep 17 00:00:00 2001 From: Kay Sievers Date: Fri, 7 Nov 2008 01:37:21 +0100 Subject: [PATCH] avr: struct device - replace bus_id with dev_name(), dev_set_name() (I did not compile or test it, please let me know, or help fixing it, if something is wrong with the conversion) This patch is part of a larger patch series which will remove the "char bus_id[20]" name string from struct device. The device name is managed in the kobject anyway, and without any size limitation, and just needlessly copied into "struct device". To set and read the device name dev_name(dev) and dev_set_name(dev) must be used. If your code uses static kobjects, which it shouldn't do, "const char *init_name" can be used to statically provide the name the registered device should have. At registration time, the init_name field is cleared, to enforce the use of dev_name(dev) to access the device name at a later time. We need to get rid of all occurrences of bus_id in the entire tree to be able to enable the new interface. Please apply this patch, and possibly convert any remaining remaining occurrences of bus_id. We want to submit a patch to -next, which will remove bus_id from "struct device", to find the remaining pieces to convert, and finally switch over to the new api, which will remove the 20 bytes array and does no longer have a size limitation.
