iommu/amd: Fix line-break in error log reporting
Browse files Browse the repository at this point in the history 
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.
