Building with gcc-5.2 raises this warning: drivers/misc/cros_ec_sandbox.c: In function cros_ec_sandbox_packet: drivers/misc/cros_ec_sandbox.c:483:5: warning: len may be used uninitialized in this function [-Wmaybe-uninitialized] if (len < 0) ^ If the function process_cmd() is called with req_hdr->command == EC_CMD_ENTERING_MODE, the value of len will be returned uninitialized.
