[PATCH v4 15/17] media: venus: Introduce accessors for remapped hfi_buffer_reqs members

[PATCH v4 15/17] media: venus: Introduce accessors for remapped hfi_buffer_reqs members
Posted by Konrad Dybcio 2 years, 3 months ago 
Currently we have macros to access these, but they don't provide a
way to override the remapped fields. Replace the macros with actual
get/set pairs to fix that.
