Subject[PATCH v2] Accessiblity: speakup: specifying the default driver parameters among the module params
Date
This is an enhancement which allows to specify the default driver
parameters among the module parameters.

Adding default variables to the speakup_soft module
allows to easily set that at boot, rather than
setting the sys variables after boot.
More details can be found here:
https://github.com/linux-speakup/speakup/issues/7

Signed-off-by: Osama Muhammad <osmtendev@gmail.com>

Changes since v1:
- Added NB_ID as the last member of enum default_vars_id.
- Added NB_ID as the size of array vars.
- Made sure that that the enteries in vars are in correct order.
