[PATCH] ARM: OMAP: Release i2c_adapter after use (Siemens SX1)

[PATCH] ARM: OMAP: Release i2c_adapter after use (Siemens SX1)

[Jean Delvare]

Each call to i2c_get_adapter() must be followed by a call to
i2c_put_adapter() to release the grabbed reference. Otherwise the
reference count grows forever and the adapter can never be
unregistered.
