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 --- audio/audio.c | 10 ++-------- 1 file changed, 2 insertions(+), 8 deletions(-) (limited to 'audio') diff --git a/audio/audio.c b/audio/audio.c index e60c124de8..9d4dcc72dd 100644 --- a/audio/audio.c +++ b/audio/audio.c @@ -1131,8 +1131,6 @@ static void audio_timer (void *opaque) */ int AUD_write (SWVoiceOut *sw, void *buf, int size) { - int bytes; - if (!sw) { /* XXX: Consider options */ return size; @@ -1143,14 +1141,11 @@ int AUD_write (SWVoiceOut *sw, void *buf, int size) return 0; } - bytes = sw->hw->pcm_ops->write (sw, buf, size); - return bytes; + return sw->hw->pcm_ops->write(sw, buf, size); } int AUD_read (SWVoiceIn *sw, void *buf, int size) { - int bytes; - if (!sw) { /* XXX: Consider options */ return size; @@ -1161,8 +1156,7 @@ int AUD_read (SWVoiceIn *sw, void *buf, int size) return 0; } - bytes = sw->hw->pcm_ops->read (sw, buf, size); - return bytes; + return sw->hw->pcm_ops->read(sw, buf, size); } int AUD_get_buffer_size_out (SWVoiceOut *sw) -- cgit v1.2.1
