Subject: [PATCH v2] include/linux/byteorder/generic.h: fix signed/unsigned
 warnings

From: Anatol Belski <anbelski@...rosoft.com>

This fixes the warnings like below, thrown by GCC

warning: comparison of integer expressions of different signedness: \
‘int’ and ‘size_t’ {aka ‘long unsigned int’} [-Wsign-compare]
  195 |  for (i = 0; i < len; i++)
      |                ^
