This will not work as driver will write on the register irrespective
of
scm
availability.
I'm sorry, where would it do so? The second line returns from the
function inf SCM is available, so the rest of the function wouldn't be
executed.
Ah!! you are right. That would work as well.
I am ok with either way, but would recommend to keep it the existing way
as it makes it little more readable.
Best regards,
