[libvirt] [PATCH 5/6] maint: use consistent if-else braces in remaining spots
Eric Blake
eblake at redhat.com
Wed Sep 3 21:25:52 UTC 2014
I'm about to add a syntax check that enforces our documented
HACKING style of always using matching {} on if-else statements.
This patch focuses on all remaining problems, where there weren't
enough issues to warrant splitting it further.
* src/remote/remote_driver.c (doRemoteOpen): Correct use of {}.
* src/security/virt-aa-helper.c (vah_add_path, valid_path, main):
Likewise.
* src/rpc/virnetsocket.c (virNetSocketNewConnectLibSSH2):
Likewise.
* src/esx/esx_vi_types.c (esxVI_Type_FromString): Likewise.
* src/uml/uml_driver.c (umlDomainDetachDevice): Likewise.
* src/util/viralloc.c (virShrinkN): Likewise.
* src/util/virbuffer.c (virBufferURIEncodeString): Likewise.
* src/util/virdbus.c (virDBusCall): Likewise.
* src/util/virnetdev.c (virNetDevValidateConfig): Likewise.
* src/util/virnetdevvportprofile.c
(virNetDevVPortProfileGetNthParent): Likewise.
* src/util/virpci.c (virPCIDeviceIterDevices)
(virPCIDeviceWaitForCleanup)
(virPCIDeviceIsBehindSwitchLackingACS): Likewise.
* src/util/virsocketaddr.c (virSocketAddrGetNumNetmaskBits):
Likewise.
* src/util/viruri.c (virURIParseParams): Likewise.
* daemon/stream.c (daemonStreamHandleAbort): Likewise.
