From: Johan Hedberg Date: Tue, 8 Nov 2011 18:40:14 +0000 (+0200) Subject: Bluetooth: Pass full hci_dev struct to mgmt callbacks X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=744cf19eadcf4de914394e0eb227f94f4318f5e4;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git Bluetooth: Pass full hci_dev struct to mgmt callbacks The current global pending command list in mgmt.c is racy. Possibly the simplest way to fix it is to have per-hci dev lists instead of a global one (all commands that need a pending struct are hci_dev specific). This way the list can be protected using the already existing per-hci dev lock. To enable this refactoring the first thing that needs to be done is to ensure that the mgmt functions have access to the hci_dev struct (instead of just the dev id).
