From 88c80bee883e7687d2672f84fd6d0fa1cee3d348 Mon Sep 17 00:00:00 2001 From: Jakub Kicinski Date: Thu, 9 May 2019 16:14:06 -0700 Subject: net/tls: remove set but not used variables MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Commit 4504ab0e6eb8 ("net/tls: Inform user space about send buffer availability") made us report write_space regardless whether partial record push was successful or not. Remove the now unused return value to clean up the following W=1 warning: net/tls/tls_device.c: In function ‘tls_device_write_space’: net/tls/tls_device.c:546:6: warning: variable ‘rc’ set but not used [-Wunused-but-set-variable] int rc = 0; ^~ CC: Vakul Garg CC: Boris Pismenny Signed-off-by: Jakub Kicinski Reviewed-by: Dirk van der Merwe Signed-off-by: David S.
