[PATCH 1/2] libfdt: add fdt_get_property_by_offset_w helper

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

Add a new fdt_get_property_by_offset_w helper function.
It is a wrapper on the fdt_get_property_by_offset() cuntion
that returns a writable pointer to a property at a given offset.
