This is _not_ what we do with the Linux kernel. We do not require random bits of userspace to be upgraded/downgraded in lock-step with the kernel. There is absolutely no reason for this to happen in this case. The SDMA firmware is already versioned. You know what version is present. Randomly renaming stuff in a structure that represents the contents of firmware like this is just not on. I know it's taken 9 months to find this, but PLEASE do not ever do this again, and never think this kind of thing is acceptable. It isn't. -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 40Mbps down 10Mbps up. Decent connectivity at last! _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
