I couldn't find any other simple way to do it. > well, I there is another way to do that: adding a function like this (include/linux/device.h) : /** * run a callback for each registered bus type * * @data : arg passed to callback * @fn : pointer to callback */ int for_each_bus(void *data, int (*fn)(struct bus_type *bus, void *data)); which would be similar to the already existing bus_for_each_dev() and would allow to avoid exporting a global variable.
