Subject: kernel-doc: warn on badly formatted short description
X-Git-Tag: v2.6.25-rc1~487
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=77cc23b8c7f2f5ea0270bf4be31438aa38316e16;p=linux-2.6

kernel-doc: warn on badly formatted short description

Make kernel-doc warn when a function/struct/union/typedef does not contain
a properly formatted short description, such as:
 * scsi_devinfo: set up the dynamic device list
or
 * scsi_devinfo -

This warning is only generated when verbose (-v) mode is used.

Also explain the -v command line option in the -h output.
