[RFT PATCH v2 2/2] memory: fsl_ifc: fix leak of private memory on probe failure
From: Krzysztof Kozlowski
Date: Thu May 27 2021 - 11:43:53 EST
On probe error the driver should free the memory allocated for private
structure. Fix this by using resource-managed allocation.
Fixes: a20cbdeffce2 ("powerpc/fsl: Add support for Integrated Flash Controller")
