Subject: bus: fsl-mc: added missing fields to dprc_rsp_get_obj_region
structure
Git-commit: ca43fec96b439b0e957121065404c0042a730501
Patch-mainline: v5.11-rc1
References: jsc#SLE-14018
'type' and 'flags' fields were missing from dprc_rsp_get_obj_region
structure therefore the MC Bus driver was not receiving proper flags
from MC like DPRC_REGION_CACHEABLE.
