[ 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.
