Subject: [PATCH v3 05/10] misc: fastrpc: Use fastrpc_map_put in fastrpc_map_create on fail
Date: Fri,  9 Sep 2022 16:39:33 +0300	[thread overview]
Message-ID: <20220909133938.3518520-6-abel.vesa@linaro.org> (raw)
In-Reply-To: <20220909133938.3518520-1-abel.vesa@linaro.org>

Move the kref_init right after the allocation so that we can use
fastrpc_map_put on any following error case.

Signed-off-by: Abel Vesa <abel.vesa@linaro.org>
