Hi,
I am reworking my sysfs serio patches (trying to get dynamic psmouse protocol switching) and I am wondering if we could export device_attach function. Serio system allows user to request device rescan - force current driver to let go off the device and find another suitable driver. Also user can manually request device to be disconnected/connected to a driver. By having device_attach exported I could get rid of some duplicated code.
Also serio allows user to request a specific driver to be bound to a device in case there are several options (psmouse/serio_raw for example). To do that and not poke in the driver core guts too much I need something like the following:
int driver_probe_device(struct device_driver *dev, struct device *dev) { int error; dev->driver = drv; if (drv->probe) { if ((error = drv->probe(dev))) { dev->driver = NULL; return error; } } device_bind_driver(dev); return 0; }
static int bus_match(struct device * dev, struct device_driver * drv) { if (dev->bus->match(dev, drv)) return driver_probe_device(drv, dev);
return -ENODEV; }
I.e driver_probe_device is exported. Does it have a chance to be accepted?
Thanks!
