Douglas Anderson 1de452a0ed regulator: core: Allow drivers to define their init data as const ... Drivers tend to want to define the names of their regulators somewhere in their source file as "static const". This means, inevitable, that every driver out there open codes something like this: static const char * const supply_names[] = { "vcc", "vccl", }; static int get_regulators(struct my_data *data) { int i; data->supplies = devm_kzalloc(...) if (!data->supplies) return -ENOMEM; for (i = 0; i < ARRAY_SIZE(supply_names); i++) data->supplies[i].supply = supply_names[i]; return devm_regulator_bulk_get(data->dev, ARRAY_SIZE(supply_names), data->supplies); } Let's make this more convenient by doing providing a helper that does the copy. I have chosen to have the "const" input structure here be the exact same structure as the normal one passed to devm_regulator_bulk_get(). This is slightly inefficent since the input data can't possibly have anything useful for "ret" or consumer and thus we waste 8 bytes per structure. This seems an OK tradeoff for not introducing an extra structure.
