From b0fd8d18683f0d77a8e6b482771ebea82234d727 Mon Sep 17 00:00:00 2001 From: Riku Voipio Date: Wed, 23 Apr 2014 10:46:13 +0300 Subject: signal/all: remove return value from copy_siginfo_to_user Since copy_siginfo_to_user always returns 0, make it void and remove any checks for return value from calling functions.
