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")
