Deferring.\n"); Throwing an error here doesn't look to be the right thing. Ultimately we will register the cooling dev when probed again after some time. So, a pr_debug() suits more here. Also, this breaks existing exynos thermal drivers as they don't handle -EPROBE_DEFER well right now. I reached here, because one of my patches had something similar to what you wrote. Just for this file though, haven't updated any other drivers though. Will be sending you my small patchset by end of day today, please see if they make any sense at all.. -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
