3.5.7.30 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Alex Deucher <alexander.deucher@xxxxxxx>
commit d195178297de9a91246519dbfa98952b70f9a9b6 upstream.
The hw i2c engines are disabled by default as the
current implementation is still experimental. Print
a warning when users enable it so that it's obvious
when the option is enabled.
v2: check for non-0 rather than 1
