[PATCH 4.19 120/243] iommu/amd: Fix line-break in error log reporting
From: Greg Kroah-Hartman
Date: Wed Dec 11 2019 - 10:21:32 EST
From: Joerg Roedel <jroedel@xxxxxxx>
[ Upstream commit 1a21ee1aabf7ff9484f2eb122476d80c7f60a620 ]
With the switch to dev_err for reporting errors from the
iommu log there was an unwanted newline introduced. The
reason was that the reporting was done in multiple dev_err()
calls, and dev_err adds a newline after every call.
Fix it by printing the log messages with only one dev_err()
call.
