[PATCH 1/1] drm/mediatek: Remove redundant error printing in mtk_dsi_probe()

[PATCH 1/1] drm/mediatek: Remove redundant error printing in mtk_dsi_probe()

[Zhen Lei]

When devm_ioremap_resource() fails, a clear enough error message will be
printed by its subfunction __devm_ioremap_resource(). The error
information contains the device name, failure cause, and possibly resource
information.

Therefore, remove the error printing here to simplify code and reduce the
binary size.

Hi everybody,
  Please ignore this patch and other "drm/mediatek". Looks like it would be better to combine them into a single patch.
