[PATCH v3 18/20] drm/dp: Convert drm_dp_helper.c to using drm_err/drm_dbg_*()

Now that we've added a back-pointer to drm_device to drm_dp_aux, made
drm_dp_aux available to any functions in drm_dp_helper.c which need to
print to the kernel log, and ensured all of our logging uses a consistent
format, let's do the final step of the conversion and actually move
everything over to using drm_err() and drm_dbg_*().
This was done by using the following cocci script:
@@
expression list expr;
@@
(
- DRM_DEBUG_KMS(expr);
+ drm_dbg_kms(aux->drm_dev, expr);
|
- DRM_DEBUG_DP(expr);
+ drm_dbg_dp(aux->drm_dev, expr);
|
- DRM_DEBUG_ATOMIC(expr);
+ drm_dbg_atomic(aux->drm_dev, expr);
|
- DRM_DEBUG_KMS_RATELIMITED(expr);
+ drm_dbg_kms_ratelimited(aux->drm_dev, expr);
|
- DRM_ERROR(expr);
+ drm_err(aux->drm_dev, expr);
)
Followed by correcting the resulting line-wrapping in the results by hand.
v2:
* Fix indenting in drm_dp_dump_access
