[PATCH v1 1/3] dmaengine: dw: Remove error message from DT parsing code

From: Andy Shevchenko
Date: Mon Aug 02 2021 - 14:43:37 EST


Users are a bit frightened of the harmless message that tells that
DT is missed on ACPI-based platforms. Remove it for good, it will
simplify the future conversion to fwnode and device property APIs.

Fixes: a9ddb575d6d6 ("dmaengine: dw_dmac: Enhance device tree support")
Depends-on: f5e84eae7956 ("dmaengine: dw: platform: Split OF helpers to separate module")
