tls: Fixed uninitialised vars warning
In tls_sw_sendmsg() and tls_sw_sendpage(), it is possible that the uninitialised variable 'ret' gets passed to sk_stream_error(). So initialise local variable 'ret' to '0. The warnings were detected by 'smatch' tool. Fixes: a42055e8d2c3 ("net/tls: Add support for async encryption") Signed-off-by: Vakul Garg <vakul.garg@nxp.com> Signed-off-by: David S.
