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.
