Subject: [PATCH 6.6 556/638] remoteproc: stm32: Fix incorrect type assignment returned by stm32_rproc_get_loaded_rsc_tablef

From: Arnaud Pouliquen <arnaud.pouliquen@...s.st.com>

[ Upstream commit c77b35ce66af25bdd6fde60b62e35b9b316ea5c2 ]

The sparse tool complains about the remove of the _iomem attribute.

stm32_rproc.c:660:17: warning: cast removes address space '__iomem' of expression

Add '__force' to explicitly specify that the cast is intentional.
This conversion is necessary to cast to addresses pointer,
which are then managed by the remoteproc core as a pointer to a
resource_table structure.
