[Intel-gfx] [PATCH v4 2/3] drm/i915/hdcp: Move away from master naming to arbiter
Suraj Kandpal
suraj.kandpal at intel.com
Mon May 29 11:07:39 UTC 2023
Rename variables to move away from master convention to
arbiter
%s/hdcp.master/hdcp.arbiter
%s/i915_hdcp_master/i915_hdcp_arbiter
%s/comp_master/comp_arbiter
--v2
- delete i915_hdcp_comp_master redundant declaration [Chaitanya]
- use %s/foo/bar/ format in commit message to show changes [Chaitanya]
--v3
- replace i915_hdcp_comp_master declaration with i915_hdcp_arbiter
to avoid any compile fail with old compilers [Chaitanya]
