[PATCH v2 2/3] iio: adc: xilinx-ams: use device_* to iterate over device child nodes

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

 



Use `device_for_each_child_node_scoped()` in `ams_parse_firmware()`
to explicitly state device child node access, and simplify the child
node handling as it is not required outside the loop.
