[PATCH] scx200_acb: Fix return on init error
The scx200_acb driver shouldn't return failure after initialization if it successfully registered at least one i2c_adapter, else we are leaking resources. The driver was OK in that respect up to 2.6.16, a recent change broke it. This is part of the fix to bug #6445.
