Subject: [PATCH v2 06/17] perf tools: Refactor error path in cs_etm_decoder__new()
Date: Fri, 24 May 2019 11:34:57 -0600 [thread overview]
Message-ID: <20190524173508.29044-7-mathieu.poirier@linaro.org> (raw)
In-Reply-To: <20190524173508.29044-1-mathieu.poirier@linaro.org>
There is no point in having two different error goto statement since
the openCSD API to free a decoder handles NULL pointers. As such
function cs_etm_decoder__free() can be called to deal with all
aspect of freeing decoder memory.
