[PATCH v3 0/5] firmware: raspberrypi: Style cleanups and fix child device lifetime

[Sander Speetjens <sander.speetjens@gmail.com>]

This series does minor style cleanups in the Raspberry Pi firmware
driver and fixes the lifetime handling of the hwmon, clock and rtc child
devices.

The first five patches address checkpatch warnings (missing blank lines
after declarations, incorrect indentation, unnecessary braces, and
undocumented memory barriers).

The final patch moves the hwmon, clock and rtc platform device pointers from
globals into struct rpi_firmware. This pairs their lifetime with the
parent device and prevents leaks or incorrect unregistration if the
driver is probed more than once. It also checks the return value of
platform_device_register_data() so that an error pointer is never
stored. Registration failures are not propagated because the child
devices are optional.
