Hi,
this is nothing dramatic, just whitespace cleanup and one error
logging line deletion. Sending it as preparation for SGI Indigo2
related patches which I'm unsure ever happens as my machine
stopped working few days ago.

eisa_probe()

Wow, a blast from the past. Careful, at the third patch, you become the
maintainer... ;-)
My own Indigo2 is unfortunately long dead, and the only EISA machine I
have left is an Alpha Jensen (and it hasn't been powered on in about 8
years).
For these two patches:
Acked-by: Marc Zyngier <[email protected]>
Thanks,
