[PATCH v2 0/2] fix an overflow error on sc27xx power supply

[Chunyan Zhang]

From: Chunyan Zhang <chunyan.zhang@xxxxxxxxxx>

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@xxxxxxxxx>.

  math64: New DIV_S64_ROUND_CLOSEST helper
