From ef759e4a28c88965972c815af6023f41bd733316 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Mon, 7 Sep 2020 13:13:06 +0300 Subject: dmaengine: dmatest: Print error codes as signed value When we got an error from DMA mapping API we convert a negative value to unsigned long type and hence make user confused: result #1: 'src mapping error' with src_off=0x19a72 dst_off=0xea len=0xccf4 (18446744073709551604) Change this to print error codes as signed values.
