[PATCH v2 46/47] tty: vt: fix up kernel-doc
From: Jiri Slaby (SUSE)
Date: Mon Jan 22 2024 - 06:19:33 EST
selection.c and vt.c still uses tabs in the kernel-doc. This misrenders the
functions in the output -- sphinx misinterprets the description. So
remove these tabs, incl. those around dashes.
'enum' keyword is needed before enum names. Fix that.
Superfluous \n after the comments are also removed. They are not
completely faulty, but this unifies all the kernel-doc in the files.
Finally fix up the cross references.
