driver core: have match() callback in struct bus_type take a const * 2024-07-03T13:16:54+00:00 Greg Kroah-Hartman gregkh@linuxfoundation.org 2024-07-01T12:07:37+00:00 d69d804845985c29ab5be5a4b3b1f4787893daf8 In the match() callback, the struct device_driver * should not be changed, so change the function callback to be a const *. This is one step of many towards making the driver core safe to have struct device_driver in read-only memory. Because the match() callback is in all busses, all busses are modified to handle this properly. This does entail switching some container_of() calls to container_of_const() to properly handle the constant *. For some busses, like PCI and USB and HV, the const * is cast away in the match callback as those busses do want to modify those structures at this point in time (they have a local lock in the driver structure.)
