[F/G/H/Unstable][SRU][PATCH 0/1] selftests/powerpc/eeh: increase timeout for eeh-basic

[Po-Hsu Lin]

[Impact]
The breakable devices test is hardware-dependent. In our test pool
it will take about:
* 30 seconds to run on a Power8 system that with 5 breakable devices,
* 60 seconds to run on a Power9 system that with 4 breakable devices.

The default 45 seconds kselftest framework timeout is not enough to
allow this test to finish on some nodes. Thus causing this test to
fail with TIMEOUT error.

[Fix]
* f5eca0b279117f ("selftests/powerpc/eeh: disable kselftest timeout
setting for eeh-basic")

We have this testcase since Focal, and this patch can be cherry-picked
into all affected releases.

[Test case]
Run this test on P9 node baltar, on which this timeout issue can be
100% reproduced. With this patch applied, the test can finish without
being terminated by the default timeout.

[Where problems could occur]
This will make test takes longer to finish, but it's still being
controlled by the timeout mechanism both in the test case and
kselftest framework. It's unlikely to make the test hang forever.
