Subject: [PATCH 10/15] Accessiblity: speakup_keypc: specifying the default driver parameters among the module params
Date:   Thu, 10 Nov 2022 02:51:03 +0500

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

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