staging: tidspbridge: overwrite DSP error codes
When calling the DSP's remote functions, the DSP returns error codes different from the ones managed by the kernel, the function's return value is shared with the MPU using a shared structure. This patch overwrites those error codes by kernel specifics and deletes unnecessary code. Signed-off-by: Rene Sapiens <rene.sapiens@ti.com> Signed-off-by: Omar Ramirez Luna <omar.ramirez@ti.com>
