From: Sebastian Hesselbarth <sebastian.hesselbarth@xxxxxxxxx> 3.12-stable review patch. If anyone has any objections, please let me know. =============== commit 7b119fd1bdc59a8060df5b659b9f7a70e0169fd6 upstream. It is good practice to mask and clear pending irqs on init. We already mask all irqs, so also clear the bridge irq cause register.
