From: kernel test robot <lkp@xxxxxxxxx> drivers/acpi/pci_root.c:150:37-38: WARNING: Use ARRAY_SIZE Use ARRAY_SIZE instead of dividing sizeof array with sizeof an element Semantic patch information: This makes an effort to find cases where ARRAY_SIZE can be used such as where there is a division of sizeof the array by the sizeof its first element or by any indexed element or the element type. It replaces the division of the two sizeofs by ARRAY_SIZE.
