ARM: OMAP: Release i2c_adapter after use (Siemens SX1)
PATCH 1/1 ARM: OMAP: Release i2c_adapter after use (Siemens SX1)
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.
