With the help of ptr_ret.cocci, I find some place to use
PTR_ERR_OR_ZERO directly.

zhong jiang (4):
  bus: ti-sysc: Use PTR_ERR_OR_ZERO rather than its implementation
  misc: mic: Use PTR_ERR_OR_ZERO rather than its implementation
  phy: tegra: Use PTR_ERR_OR_ZERO rather than its implementation
  rtc: ds1347: Use PTR_ERR_OR_ZERO rather than its implementation
