Rafal Ostrowski c1199393ec drm/amd/display: Refactor surface_update_flags to flat struct with helpers ... [Why] The union surface_update_flags type uses a union with a raw uint32_t member to allow bulk clear/set/test operations on the bitfield. This couples the struct layout to a specific integer width, breaks when the number of flag bits exceeds 32, and scatters raw-access patterns across many call sites. Replacing the union with a plain struct and adding explicit helper functions makes the intent clearer and prepares the code for future flag-set expansion. [How] Rename union surface_update_flags to struct pipe_update_bits and remove the union wrapper, the .bits sub-struct, and the .raw member. Add inline helpers in dc.h: surface_update_flags_clear(), surface_update_flags_set_full(), and surface_update_flags_is_any_set() that operate on the new struct via memset/memcmp. Add stream_update_flags_clear() and stream_update_flags_set_full() in dc_stream.h for the stream update flags union. Update all callers: change the type name, replace .bits.field with .field, replace .raw = 0 with the clear helper, replace .raw = 0xFFFFFFFF with the set_full helper, and replace .raw boolean tests with is_any_set.
