Re: [PATCH] selftests: rtc: Support harness test filtering and arguments

[sashiko-bot@kernel.org]

> rtctest implements its own main() function with a rigid switch (argc)
> check that only accepts an optional single argument for the RTC device
> node path. This prevents kselftest_harness standard arguments from
> working properly:
> 
> 1. Passing filter options like -t <name> or -T <name> triggers a usage
>    error because argc is greater than 2.
> 2. Passing -l or -h causes rtctest to treat "-l" or "-h" as the device
>    node path and fail with access() errors before ever reaching the
>    harness argument checker.

> test_harness_run(), while preserving the ability to specify an optional
> RTC device node path as a non-option argument. Also ensure optind is
> reset before invoking test_harness_run() so the harness can inspect the
