[Qemu-devel] [PATCH 00/11] trivial: Remove superfluous '\n' around error_report/error_setg

[Qemu-devel] [PATCH 00/11] trivial: Remove superfluous '\n' around error_report/error_setg

[arei.gonglei]

From: Gonglei <arei.gonglei@huawei.com>

Yestoday, I found that some files have superflous '\n' charactor
around error_report/error_setg when reviewed patches.

By a simply script, the below files were listed. Classify and fix
them. It's suitable for appling via qemu-trivial IMHO.
 

Gonglei (11):
  block: remove superfluous '\n' around error_report/error_setg
  a9gtimer: remove superfluous '\n' around error_setg
  pl330.c: remove superfluous '\n' around error_setg
  numa: remove superfluous '\n' around error_setg
  Remove superfluous '\n' around error_report()
  vhost-scsi: Remove superfluous '\n' around error_report()
  vfio: Remove superfluous '\n' around error_report()
  xtensa: Remove superfluous '\n' around error_report()
  tpm: Remove superfluous '\n' around error_report()
  arm/digic_boards: Remove superfluous '\n' around error_report()
  vhost: Remove superfluous '\n' around error_report()

When I fixed this before, I didn't split it up (commits 312fd5f 6daf194
be62a2eb).  Splitting it up is fine, of course.  Having the catch-all as
PATCH 05/11 is a bit odd, though.  Its qemu-img.c hunk could go into
PATCH 01, because qemu-img is part of the block subsystem.  Not worth a
respin as far as I'm concerned.

Not hugely important but there's no need in the trailing "" here and below.
