Subject: [PATCH v2 4/8] powerpc-perf/hx-24x7: Don't log failed hcall twice
Date: Wed, 28 Jun 2017 20:10:22 -0300	[thread overview]
Message-ID: <20170628231026.23190-5-bauerman@linux.vnet.ibm.com> (raw)
In-Reply-To: <20170628231026.23190-1-bauerman@linux.vnet.ibm.com>

make_24x7_request already calls log_24x7_hcall if it fails, so callers
don't have to do it again.

In fact, since the latter is now only called from the former, there's no
need for a separate log_24x7_hcall anymore so remove it.
