[Freedreno] [PATCH v2] drm/msm/dpu: Clean up CRC debug logs

[Stephen Boyd]

Quoting Jessica Zhang (2022-04-29 17:52:10)
> Currently, dpu_hw_lm_collect_misr returns EINVAL if CRC is disabled.
> This causes a lot of spam in the DRM debug logs as it's called for every
> vblank.
>
> Instead of returning EINVAL when CRC is disabled in
> dpu_hw_lm_collect_misr, let's return ENODATA and add an extra ENODATA check
> before the debug log in dpu_crtc_get_crc.

> Changes since V1:
