From: Stephen Warren <[email protected]> If a regmap has a cache, it's likely that registers are not volatile, perhaps with exceptions. Otherwise, the cache would not be useful. Encode this assumption into regmap_volatile()'s default return value, for the case where a regmap doesn't specify which registers are volatile.
