memory: ti-emif-pm: Drop of_match_ptr from of_device_id table

2021-02-08T17:13:24Z

The driver can match only via the DT table so the table should be always used and the of_match_ptr does not have any sense (this also allows ACPI matching via PRP0001, even though it might be not relevant here).

amba: Make the remove callback return void

2021-02-02T13:25:50Z

All amba drivers return 0 in their remove callback. Together with the driver core ignoring the return value anyhow, it doesn't make sense to return a value here. Change the remove prototype to return void, which makes it explicit that returning an error value doesn't work as expected. This simplifies changing the core remove callback to return void, too.
