+Subject: [PATCH] connect has a different signature on musl
+
+On linux when not using glibc and using musl for C library, connect
+API has a different signature, this patch fixes this so it can compile
+on musl, the functionality should remain same as it is immediately
+typcasted to struct sockaddr_in* type inside the function before use
+
+Upstream-Status: Pending
