Subject: drm/i915/fb: Rename i915_color_plane_view::stride to mapping_stride
Git-commit: be6c1dd5ac074defdfb1471d28e0bb6eedfe3ae5
Patch-mainline: v5.17-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225
The next patch needs to distinguish between a view's mapping and scanout
stride. Rename the current stride parameter to mapping_stride with the
script below. mapping_stride will keep the same meaning as stride had
on all platforms so far, while the meaning of it will change on ADLP.
No functional changes.
