I tested this v3 patch set with 4.2-rc5 and it works fine on my X-Gene arm64 platform. The only problem is 'git am' will complain (due to line offset changed, I guess). Using 'patch -p 1' to apply the 2 patches is fine. I will repost the whole set over 4.2-rc5. > > Let me apply and see if it still work as is. > > -Loc -- Regards, Duc Dang. -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
