From 9be385980d37e8f4fd33f605f5fb1c3d144170a8 Mon Sep 17 00:00:00 2001 From: Eduardo Habkost Date: Mon, 13 Jun 2016 18:57:58 -0300 Subject: coccinelle: Remove unnecessary variables for function return value Use Coccinelle script to replace 'ret = E; return ret' with 'return E'. The script will do the substitution only when the function return type and variable type are the same. Manual fixups: * audio/audio.c: coding style of "read (...)" and "write (...)" * block/qcow2-cluster.c: wrap line to make it shorter * block/qcow2-refcount.c: change indentation of wrapped line * target-tricore/op_helper.c: fix coding style of "remainder|quotient" * target-mips/dsp_helper.c: reverted changes because I don't want to argue about checkpatch.pl * ui/qemu-pixman.c: fix line indentation * block/rbd.c: restore blank line between declarations and statements Reviewed-by: Eric Blake Signed-off-by: Eduardo Habkost Message-Id: <1465855078-19435-4-git-send-email-ehabkost@redhat.com> Reviewed-by: Markus Armbruster [Unused Coccinelle rule name dropped along with a redundant comment; whitespace touched up in block/qcow2-cluster.c; stale commit message paragraph deleted] Signed-off-by: Markus Armbruster --- hw/intc/s390_flic_kvm.c | 5 ++--- 1 file changed, 2 insertions(+), 3 deletions(-) (limited to 'hw/intc') diff --git a/hw/intc/s390_flic_kvm.c b/hw/intc/s390_flic_kvm.c index 680857f0c7..fef808011f 100644 --- a/hw/intc/s390_flic_kvm.c +++ b/hw/intc/s390_flic_kvm.c @@ -195,7 +195,7 @@ static int kvm_s390_register_io_adapter(S390FLICState *fs, uint32_t id, .swap = swap, }; KVMS390FLICState *flic = KVM_S390_FLIC(fs); - int r, ret; + int r; struct kvm_device_attr attr = { .group = KVM_DEV_FLIC_ADAPTER_REGISTER, .addr = (uint64_t)&adapter, @@ -208,8 +208,7 @@ static int kvm_s390_register_io_adapter(S390FLICState *fs, uint32_t id, r = ioctl(flic->fd, KVM_SET_DEVICE_ATTR, &attr); - ret = r ? -errno : 0; - return ret; + return r ? -errno : 0; } static int kvm_s390_io_adapter_map(S390FLICState *fs, uint32_t id, -- cgit v1.2.1
