Subject: [PATCH 08/15] Accessiblity: speakup_dtlk: specifying the default driver parameters among the module params
Date:   Thu, 10 Nov 2022 02:51:01 +0500
Message-Id: <20221109215108.7933-9-osmtendev@gmail.com>

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:
