From 426e2c6a2c383c9b1f9c74b7815252da89b3b8ab Mon Sep 17 00:00:00 2001 From: "Maciej W. Rozycki" Date: Sun, 21 Mar 2021 20:55:22 +0100 Subject: pata_legacy: Properly document module parameters Most pata_legacy module parameters lack MODULE_PARM_DESC documentation and none is described in kernel-parameters.txt. Also several comments are inaccurate or wrong. Add the missing documentation pieces then and reorder parameters into a consistent block. Remove inaccuracies as follows: - `all' affects primary and secondary port ranges only rather than all, - `probe_all' affects tertiary and further port ranges rather than all, - `ht6560b' is for HT 6560B rather than HT 6560A.
