Sami Tolvanen 55e6f8b3c0 treewide: Change list_sort to use const pointers ... [ Upstream commit 4f0f586bf0c898233d8f316f471a21db2abd522d ] list_sort() internally casts the comparison function passed to it to a different type with constant struct list_head pointers, and uses this pointer to call the functions, which trips indirect call Control-Flow Integrity (CFI) checking. Instead of removing the consts, this change defines the list_cmp_func_t type and changes the comparison function types of all list_sort() callers to use const pointers, thus avoiding type mismatches.
