Subject: [PATCH 1/1] kbuild: Optimize tests and remove shadowed local variable.

Removes an unnecessary shadowed local variable (start).
Optimize test of isdigit:
- If isalpha returns true, isdigit will return false, so no need to test.

This patch was sent to me, but maybe belong to David's field.

David, will you take care of this patch?

https://lore.kernel.org/patchwork/patch/988171/

I think the commit subject should be changed kbuild: -> ASN.1:


Anyway, this patch looks trivial,
FWIW

Hello David,

My name is Leonardo and I am new to kernel development.

Is this patch acceptable? Do it need some rework? The change makes sense?
Is there a way to better follow the workflow for this patch?

Please let me know if it needs anything.

Best regards,

Leonardo Bras

I thought David would pick this up,
but he is not responding.

Now, applied to my kbuild tree.
