You say we need this in prep for shared instances, which is fair, but
shared instances should presumably share across the same driver, most
of the time? So perhaps we should do a similar thing here as you did to
the bus/dev name? Maybe when shared instance is allocated:
devlink->driver_name = kasprintf("%s+", dev->driver);
And then:
+const char *devlink_dev_driver_name(const struct devlink *devlink)
+{
+ struct device *dev = devlink->dev;
+
+ return dev ? dev->driver->name : devlink->driver_name;
+}
+EXPORT_SYMBOL_GPL(devlink_dev_driver_name);
?
Good idea. Will add is in some form.
