From: Chunyan Zhang <chunyan.zhang@unisoc.com>
The patch 2/2 fixes an overflow error by changing to 64-bit divide operations. In order to avoid compile error on 32-bit architectures, this patchset also introduced a new 64-bit helper in patch 1/2.
Changes since v1: (https://lkml.org/lkml/2020/7/17/63) - Added new help macro DIV_S64_ROUND_CLOSEST; - Fixed an error reported by kernel test robot <lkp@intel.com>.
Chunyan Zhang (2): math64: New DIV_S64_ROUND_CLOSEST helper power: supply: sc27xx: prevent adc * 1000 from overflow
