Subject: Bluetooth: mgmt: Fix Set SSP supported check
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6c8f12c143fe83485afa530320e6f70dfc1aad54;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

Bluetooth: mgmt: Fix Set SSP supported check

The test for SSP support needs to be earlier in the set_ssp function so
that we return an error when SSP is not supported even when the device
is powered off.
