Subject: [PATCH] i2c-i801: Don't depend on other kernel driver config options
Date: Fri, 13 May 2011 12:01:00 +0200	[thread overview]
Message-ID: <20110513120100.4d47410a@endymion.delvare> (raw)

Don't let other driver config options influence us, as it makes the
code more complex and fragile for a small benefit. There's nothing
wrong with instantiating I2C devices even if they don't have a driver.
And we're talking about 835 extra bytes in the binary on x86-64,
that's hardly worth arguing about.

David, would this make you feel better? Hans, any objection?
