From 8419702489f3be7f9e4fcf12c04d9d3f00114d35 Mon Sep 17 00:00:00 2001 From: Logan Gunthorpe Date: Wed, 27 Jul 2022 13:15:22 -0600 Subject: [PATCH] dma-mapping: reformat comment to suppress htmldoc warning 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.
