pcmcia: cs: make pcmcia_socket_class constant

2024-03-10T08:07:00Z

Since commit 43a7206b0963 ("driver core: class: make class_register() take a const *"), the driver core allows for struct class to be in read-only memory, so move the pcmcia_socket_class structure to be declared at build time placing it into read-only memory, instead of having to be dynamically allocated at boot time.

pcmcia: ds: make pcmcia_bus_type const

2024-02-18T16:39:43Z

Now that the driver core can properly handle constant struct bus_type, move the pcmcia_bus_type variable to be a constant structure as well, placing it into read-only memory which can not be modified at runtime.

pcmcia: xxs1500_ss: Convert to platform remove callback returning void

2023-12-15T16:07:28Z

The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new(), which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.
