rtc: use simple i2c probe

2022-06-24T19:24:02+00:00

All these drivers have an i2c probe function which doesn't use the
"struct i2c_device_id *id" parameter, so they can trivially be
converted to the "probe_new" style of probe with a single argument.

This change was done using the following Coccinelle script, and fixed
up for whitespace changes:

@ rule1 @
identifier fn;
identifier client, id;
@@

- static int fn(struct i2c_client *client, const struct i2c_device_id *id)
+ static int fn(struct i2c_client *client)
{
...when != id
}

@ rule2 depends on rule1 @
identifier rule1.fn;
identifier driver;
@@

struct i2c_driver driver = {
-	.probe
+	.probe_new
		=
(
		   fn
|
-		   &fn
+		   fn
)
		,
};

rtc: rework rtc_register_device() resource management

2020-11-19T11:50:12+00:00

rtc_register_device() is a managed interface but it doesn't use devres
by itself - instead it marks an rtc_device as "registered" and the devres
callback for devm_rtc_allocate_device() takes care of resource release.

This doesn't correspond with the design behind devres where managed
structures should not be aware of being managed. The correct solution
here is to register a separate devres callback for unregistering the
device.

While at it: rename rtc_register_device() to devm_rtc_register_device()
and add it to the list of managed interfaces in devres.rst. This way we
can avoid any potential confusion of driver developers who may expect
there to exist a corresponding unregister function.

rtc: remove superfluous error message

The RTC core now has error messages in case of registration failure, there
is no need to have other messages in the drivers.
