| |
In staging/netlogic/platform.c Refactoring the identical code used in several places for calculating the physical address of memory-mapped objects on the device.Put that into an inline helper function and use it.
Adjust the types of arguments of xlr_resource_init() - 'offset' and 'irq' are actually unsigned. The values passed to those fit into 0..2G range, so the behaviour is unchanged, but it's more consistent that way.
