In iwl_dbgfs_mem_read(), the len variable may become negative and is
compared to < 0 (an error case). Comparing size_t (which is unsigned)
to < 0 causes a warning on certain platforms (like i386):
drivers/net/wireless/intel/iwlwifi/mvm/debugfs.c:1561:5-8: WARNING: Unsigned expression compared with zero: len < 0
To prevent that, use ssize_t for len instead.
