See SKY2_DEBUG After looking through the kernel, there doesn't seem to be a clear precedence for this. As was pointed out, SKY2_DEBUG is an optional configuration on its own. However regmap uses debugfs, and it is only optional based on CONFIG_DEBUG_FS, which is how this patch is currently set up. This patch does not have much overhead and we would prefer that it be enabled with CONFIG_DEBUG_FS. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
