Subject: [Intel-gfx] [PATCH i-g-t v2 15/16] tests/core_hotunplug: Explicitly ignore unused return values
Date: Fri,  7 Aug 2020 11:20:01 +0200	[thread overview]
Message-ID: <20200807092002.32350-16-janusz.krzysztofik@linux.intel.com> (raw)
In-Reply-To: <20200807092002.32350-1-janusz.krzysztofik@linux.intel.com>

Some return values are not useful and can be ignored.  Wrap those cases
inside igt_ignore_warn(), not only to make sure compilers are happy but
also to clearly document our decisions.

v2: Rebase on current upstream master.
