4 Subject: [PATCH] drm/vc4: hvs: Use pointer to HVS in HVS_READ and
5 HVS_WRITE macros
6
7 Those macros are really about the HVS itself, and thus its associated
8 structure vc4_hvs, rather than the entire (virtual) vc4 device.
9
10 Let's change those macros to use the hvs pointer directly, and change
11 the calling sites accordingly.
