Subject: [BLUETOOTH] sco: Possible double free.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=cdee5751bf91d02616aaf30a5affef56105e3b79;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

[BLUETOOTH] sco: Possible double free.

this fixes coverity bug id #1068.
hci_send_sco() frees skb if (skb->len > hdev->sco_mtu).
Since it returns a negative error value only in this case, we
can directly return here.
