Subject: NFC: double unlock in nfc_llcp_recv_connect()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=341ee4349f31e42fb0eb20d340d15309ac760308;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

NFC: double unlock in nfc_llcp_recv_connect()

We unlock inside the if block on the other side of this if else
statement.  It could result in calling mutex_unlock() twice.
