Subject: [PATCH] kernel-doc: describe the ``literal`` syntax
Git-commit: 5d47c31b59f6c2c7ddce0fcb1be0f85ad39a56fe

References: bsc#1079840

changeset b97f193abf83 ("scripts/kernel-doc: fix parser
for apostrophes") added support for ``literal`` inside
kernel-doc, in order to allow using the "%" symbol inside
a literal block, as this is used at printk() description.

Document it.

+  A literal block that should be handled as-is. The output will use a
