[PATCH v2 04/12] drm: panel: replace dev_* with DRM_DEV_* equivalent in panel-simple

[Aastha Gupta]

For drivers which could have multiple instances, it is necessary to
differentiate between which is which in the logs. Since
DRM_INFO/WARN/ERROR don’t do this, drivers used dev_info/warn/err to
make this differentiation. We now have DRM_DEV_* variants of the drm
print macros, so we can start to convert those drivers back to using
drm-formatted specific log messages.

This patch is using following Coccinelle script:

(
- dev_info
+ DRM_DEV_INFO

- dev_err
+ DRM_DEV_ERROR
|
- dev_dbg
+ DRM_DEV_DEBUG
)
