From 88dce45b3282647ac0b2916d4820956cd239a1e9 Mon Sep 17 00:00:00 2001 From: Osama Muhammad Date: Thu, 10 Nov 2022 02:51:04 +0500 Subject: Accessiblity: speakup_ltlk: specifying the default driver parameters among the module params This is an enhancement which allows to specify the default driver parameters among the module parameters. Adding default variables to the speakup_ltlk module allows to easily set that at boot, rather than setting the sys variables after boot.
