net/tls: remove set but not used variables
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 <vakul.garg@nxp.com> CC: Boris Pismenny <borisp@mellanox.com> Signed-off-by: Jakub Kicinski <jakub.kicinski@netronome.com> Reviewed-by: Dirk van der Merwe <dirk.vandermerwe@netronome.com> Signed-off-by: David S.
