[PATCH v4 16/17] drm/dp_dual_mode: Convert drm_dp_dual_mode_helper.c to using drm_err/drm_dbg_kms()

From: Lyude Paul
Date: Fri Apr 23 2021 - 14:46:08 EST


Next step in the conversion, move everything in drm_dp_dual_mode_helper.c
over to using drm_err() and drm_dbg_kms(). This was done using the
following cocci script:

@@
expression list expr;
@@

(
- DRM_DEBUG_KMS(expr);
+ drm_dbg_kms(dev, expr);
|
- DRM_ERROR(expr);
+ drm_err(dev, expr);
)

And correcting the indentation of the resulting code by hand.
