modpost: squash if...else-if in find_elf_symbol2()
if ((addr - sym->st_value) < distance) {
distance = addr - sym->st_value;
near = sym;
} else if ((addr - sym->st_value) == distance) {
near = sym;
}
is equivalent to:
if (addr - sym->st_value <= distance) {
distance = addr - sym->st_value;
near = sym;
}
(The else-if block can overwrite 'distance' with the same value).
