Subject: Bluetooth: Ignore SMP data on non-LE links
X-Git-Tag: accepted/tizen/common/20141203.182822~719^2~3^2^2~307^2~61
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=3432711f49c31c8f21f8a9beb0b3d4b2c7bc9dc2;p=platform%2Fkernel%2Flinux-arm64.git

Bluetooth: Ignore SMP data on non-LE links

The SMP CID is only defined for LE transports. Instead of returning an
error from smp_sig_channel() in this case (which would cause a
disconnection) just return 0 to ignore the data, which is consistent
with the behavior for other unknown CIDs.
