Subject: [PATCH 3.19.y-ckt 144/155] i2c: mv64xxx: really allow I2C offloading

3.19.8-ckt10 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Hezi Shahmoon <hezi@...vell.com>

commit 0729a04977d497cf66234fd7f900ddcec3ef1c52 upstream.

Commit 00d8689b85a7 ("i2c: mv64xxx: rework offload support to fix
several problems") completely reworked the offload support, but left a
debugging-related "return false" at the beginning of the
mv64xxx_i2c_can_offload() function. This has the unfortunate consequence
that offloading is in fact never used, which wasn't really the
intention.

This commit fixes that problem by removing the bogus "return false".
