From 66997c42e02c84481fc162a5b7bd6ad6c643bae2 Mon Sep 17 00:00:00 2001 From: Markus Armbruster Date: Tue, 22 Nov 2022 14:49:16 +0100 Subject: [PATCH] cleanup: Tweak and re-run return_directly.cocci MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Tweak the semantic patch to drop redundant parenthesis around the return expression. Coccinelle drops a comment in hw/rdma/vmw/pvrdma_cmd.c; restored manually. Coccinelle messes up vmdk_co_create(), not sure why. Change dropped, will be done manually in the next commit. Line breaks in target/avr/cpu.h and hw/rdma/vmw/pvrdma_cmd.c tidied up manually. Whitespace in tools/virtiofsd/fuse_lowlevel.c tidied up manually. checkpatch.pl complains "return of an errno should typically be -ve" two times for hw/9pfs/9p-synth.c. Preexisting, the patch merely makes it visible to checkpatch.pl.
