Subject: [PATCH] Accessiblity: speakup: specifying the default driver parameters among the module params
Date:   Wed, 19 Oct 2022 01:33:08 +0500
Message-Id: <20221018203308.6143-1-osmtendev@gmail.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

This is an enhancement which allows to specify the default driver
parameters among the module parameters.

Adding default variables to the speakup_acntpc.c and speakup_acntsa.c
module allows to easily set that at boot, rather than
setting the sys variables after boot.
More details can be found here:
