mfd: wm8994: Set mfd id-base for regulator devs creation to avoid conflicts (fef22cb4) · Commits · 戴 / test

After commit: ("mfd: core: Fix platform-device id generation") We must set the id base when register a duplicate name of mfd_cell. If not, duplicate filename error was reported. - sysfs: cannot create duplicate filename '/devices/.../wm8994-ldo' Signed-off-by:
