X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1e16357480fdeaeff7c5572f1afba7835473fcb6;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

Bluetooth: mgmt: Fix Set SSP check for supported feature

If the local controller doesn't support SSP we should always return an
error for the Set SSP command.
