2023-05-29misc: Switch i2c drivers back to use .probe()Uwe Kleine-König
After commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new() call-back type"), all drivers being converted to .probe_new() and then 03c835f498b5 ("i2c: Switch .probe() to not take an id parameter") convert back to (the new) .probe() to be able to eventually drop .probe_new() from struct i2c_driver. While touching these drivers, fix alignment in apds990x.c and bh1770glc.c.

.probe_new() doesn't get the i2c_device_id * parameter, so determine that explicitly in the probe function.

2022-08-16i2c: Make remove callback return voidUwe Kleine-König
The value returned by an i2c driver's remove function is mostly ignored. (Only an error message is printed if the value is non-zero that the error is ignored.) So change the prototype of the remove function to return no value. This way driver authors are not tempted to assume that passing an error to the upper layer is a good idea. All drivers are adapted accordingly. There is no intended change of behaviour, all callbacks were prepared to return 0 before.

2021-10-13misc: ad525x_dpot: Make ad_dpot_remove() return voidUwe Kleine-König
Up to now ad_dpot_remove() returns zero unconditionally. Make it return void instead which makes it easier to see in the callers that there is no error to handle. Also the return value of i2c and spi remove callbacks is ignored anyway.
