[PATCH v1] Revert "dmaengine: stm32-mdma: Add a check on read_u32_array"
From: Pierre-Yves MORDRET
Date: Mon Mar 25 2019 - 10:47:04 EST
This reverts commit 906b40b246b0acb54c4dc97e815cf734761c9820.
As stated by bindings "st,ahb-addr-masks" is optional.
The statement inserted by this commit makes this property
mandatory and prevents MDMA to be probed in case property not present.
