drm/i915/guc: Rename guc_ggtt_offset to intel_guc_ggtt_offset
GuC related exported functions should start with "intel_guc_" prefix and
pass intel_guc as the first parameter since its GuC related. Current
guc_ggtt_offset() failed to follow this code convention and this is a
problem for future patches that needs to access intel_guc data to verify
the GGTT offset against the GuC WOPCM top.
This patch renames the guc_ggtt_offset to intel_guc_ggtt_offset and updates
the related code to pass intel_guc pointer to this function call, so that
we can have a unified coding style for GuC code and also enable the future
patches to get GuC related data from intel_guc to do the offset
verification. Meanwhile, this patch also moves the GUC_GGTT_TOP from
intel_guc_regs.h to intel_guc.h since it is not GuC register related
definition.
v8:
- Fixed coding style issues and moved GUC_GGTT_TOP to intel_guc.h (Sagar)
- Updated commit message to explain to reason and motivation to add
intel_guc as the first parameter of intel_guc_ggtt_offset (Chris)
v9:
- Fixed code alignment issue due to line break (Chris)
v10:
- Removed unnecessary comments, redundant code and avoided reuse variable
to avoid potential issues (Joonas)
v13:
- Updated the ordering of s-o-b/cc/r-b tags (Sagar)
