[PATCH] Accessiblity: speakup: specifying the default driver parameters among the module params

From: Osama Muhammad
Date: Sat Oct 22 2022 - 12:14:46 EST


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:
