commit 6f10419187d0d5fe395e2a2f2a64370961bf02a3 upstream.
When building with CONFIG_MFD_88PM800 and CONFIG_REGULATOR_88PM800 enabled as loadable modules, we see the following warning:
warning: same module names found: drivers/regulator/88pm800.ko drivers/mfd/88pm800.ko
Rework so that the file is named 88pm800-regulator.
