Subject: [PATCH] Accessiblity: speakup_dtlk: specifying the default driver parameters among the module params
Date:   Wed,  2 Nov 2022 01:59:12 +0500

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

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