Hello Stefan! Just to note that I'm adding this space too when writing for-loops. E.g.:
for (i = 0; i < 10; i++) { ... }
or:
fdt_for_each_node_by_compatible (node, blob, -1, compatible) { ... }
Right. But we already have multiple of these for () helpers in U-Boot and Linux. And AFACIT all are used without this space:
[stefan@ryzen u-boot (master)]$ git grep for_each drivers/ drivers/block/blkcache.c: list_for_each_entry(node, &block_cache, lh) drivers/block/blkcache.c: list_for_each_safe(entry, n, &block_cache) { drivers/button/button-adc.c: dev_for_each_subnode(node, dev->parent) { drivers/button/button-adc.c: dev_for_each_subnode(node, parent) { drivers/button/button-gpio.c: dev_for_each_subnode(node, parent) { drivers/clk/clk-uclass.c: list_for_each_entry(child_dev, &clk->dev->child_head, sibling_node) { drivers/clk/clk_stm32mp1.c: ofnode_for_each_subnode(subnode, node) { drivers/core/device-remove.c: list_for_each_entry_safe(pos, n, &dev->child_head, sibling_node) { drivers/core/device-remove.c: list_for_each_entry_safe(pos, n, &dev->child_head, sibling_node) { drivers/core/device.c: list_for_each_entry_safe(pos, n, &dev->parent->child_head, drivers/core/device.c: list_for_each_entry(uc, gd->uclass_root, sibling_node) {
So I would prefer to also use this new helper without the extra space as well.
Thanks, Stefan
