Subject: [PATCH] dma-mapping: Reformat comment to suppress htmldoc warning
Precedence: bulk

make html doc reports a cryptic warning with the commit named below:

  kernel/dma/mapping.c:258: WARNING: Option list ends without a blank
                                     line; unexpected unindent.

Seems the parser is a bit fussy about the tabbing and having a single
space tab causes the warning. To suppress the warning add another
tab to the list and reindent everything.

Fixes: 7c2645a2a30a ("dma-mapping: allow EREMOTEIO return code for P2PDMA transfers")
