Subject: [PATCH] remoteproc: mediatek: Fix error code in scp_rproc_init()
Date: Sat, 4 May 2024 14:26:46 +0300 [thread overview]
Message-ID: <b2114e3c-fa64-4edb-a1ff-d2009e544c3f@moroto.mountain> (raw)
Set the error code to ERR_PTR(-ENOMEM). Otherwise if there is an
allocation failure it leads to a NULL dereference in the caller.
Fixes: c08a82494500 ("remoteproc: mediatek: Support setting DRAM and IPI shared buffer sizes")
