I think Lee's "Grim" comment here was that prefixing globals with "g_"
is not consistent with the Linux coding style. Just remove the "g_".

nit: with {} we have space, so:
{ RK808_BUCK3_CONFIG_REG, BUCK_ILMIN_MASK, BUCK_ILMIN_150MA },
instead of:
{RK808_BUCK3_CONFIG_REG, BUCK_ILMIN_MASK, BUCK_ILMIN_150MA},
