Subject: [PATCH v2 3/7] remoteproc: Simplify default name allocation
Date: Wed, 15 Apr 2020 14:48:54 -0600 [thread overview]
Message-ID: <20200415204858.2448-4-mathieu.poirier@linaro.org> (raw)
Message-ID: <20200415204854.nPDpKl4X8kpt5YAauT17FObOhwRX5cP1MlUk3ZmXTb8@z> (raw)
In-Reply-To: <20200415204858.2448-1-mathieu.poirier@linaro.org>
In an effort to cleanup firmware name allocation, replace the
cumbersome mechanic used to allocate a default firmware name with
function kasprintf().
