Subject: [PATCH v2 04/10] misc: fastrpc: Add fastrpc_remote_heap_alloc
Date: Fri, 2 Sep 2022 18:48:54 +0300 [thread overview]
Message-ID: <20220902154900.3404524-5-abel.vesa@linaro.org> (raw)
In-Reply-To: <20220902154900.3404524-1-abel.vesa@linaro.org>
Split fastrpc_buf_alloc in such a way it allows allocation of remote
heap too and add fastrpc_remote_heap_alloc to do so.
