[ Upstream commit c65e41538b04e0d64a673828745a00cb68a24371 ]

firmware attempts to load test modules that require root access and fail. Fix it to check for root uid and exit with skip code instead.

Before this fix:

selftests: firmware: fw_run_tests.sh modprobe: ERROR: could not insert 'test_firmware': Operation not permitted You must have the following enabled in your kernel: CONFIG_TEST_FIRMWARE=y CONFIG_FW_LOADER=y CONFIG_FW_LOADER_USER_HELPER=y CONFIG_IKCONFIG=y CONFIG_IKCONFIG_PROC=y not ok 1 selftests: firmware: fw_run_tests.sh # SKIP

With this fix:

selftests: firmware: fw_run_tests.sh skip all tests: must be run as root not ok 1 selftests: firmware: fw_run_tests.sh # SKIP
