Subject: tls: Remove dead code in tls_sw_sendmsg
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=5a3611efe5b3095f348c892d040202b2ae969f4e;p=openwrt%2Fstaging%2Fblogic.git

tls: Remove dead code in tls_sw_sendmsg

tls_push_record either returns 0 on success or a negative value on failure.
This patch removes code that would only be executed if tls_push_record
were to return a positive value.
