When running the rtctest if we pass wrong rtc device file as an argument the test fails expectedly, but prints the logs that are not useful to point out the issue. To handle this, the patch adds a checks to verify if the rtc_file is valid. Signed-off-by: Atul Kumar Pant <atulpant.linux@gmail.com> --- changes since v3: Added Linux-kselftest and Linux-kernel mailing lists. changes since v2: Changed error message when rtc file does not exist. changes since v1: Removed check for uid=0 If rtc file is invalid, then exit the test. tools/testing/selftests/rtc/rtctest.c | 11 ++++++++++- 1 file changed, 10 insertions(+), 1 deletion(-)
