From: Stefan Richter Date: Thu, 24 Jan 2008 00:53:51 +0000 (+0100) Subject: firewire: fw-cdev: use device generation, not card generation X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=cf5a56ac8083dd04ffe8b9b2ec7895e9bcff44bc;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git firewire: fw-cdev: use device generation, not card generation We have to use the fw_device.generation here, not the fw_card.generation, because the generation must never be newer than the node ID when we emit a transaction. This cannot be guaranteed with fw_card.generation. Signed-off-by: Stefan Richter Verified in concert with subsequent memory barriers patch to fix 'giving up on config rom' issues on multiple system and drive combinations that were previously affected.
