iwlwifi: mvm: use ssize_t for len in iwl_debugfs_mem_read() 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.
