	Switch to device_for_each_child_node_scoped() to simplify the code by removing the need for calls to fwnode_handle_put() in the error paths. This also prevents possible memory leaks if new error paths are added without the required call to fwnode_handle_put().

2023-11-01	leds: mt6370: Annotate struct mt6370_priv with __counted_by	Kees Cook
	Prepare for the coming implementation by GCC and Clang of the __counted_by attribute. Flexible array members annotated with __counted_by can have their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS (for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family functions). As found with Coccinelle[1], add __counted_by for struct mt6370_priv.
