From c7dabef8a2c59e6a3de9d66fc35fb6a43ef7172d Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Tue, 27 Oct 2009 13:26:47 -0600 Subject: vsprintf: use %pR, %pr instead of %pRt, %pRf Jesse accidentally applied v1 [1] of the patchset instead of v2 [2]. This is the diff between v1 and v2. The changes in this patch are: - tidied vsprintf stack buffer to shrink and compute size more accurately - use %pR for decoding and %pr for "raw" (with type and flags) instead of adding %pRt and %pRf [1] http://lkml.org/lkml/2009/10/6/491 [2] http://lkml.org/lkml/2009/10/13/441 Signed-off-by: Bjorn Helgaas Signed-off-by: Jesse Barnes --- arch/ia64/pci/pci.c | 11 ++++--- arch/x86/pci/acpi.c | 7 +++-- arch/x86/pci/i386.c | 11 +++---- drivers/pci/pci.c | 2 +- drivers/pci/probe.c | 17 ++++++----- drivers/pci/quirks.c | 2 +- drivers/pci/setup-bus.c | 79 ++++++++++++++++++++++--------------------------- drivers/pci/setup-res.c | 20 +++++++------ drivers/pnp/quirks.c | 5 ++-- drivers/pnp/resource.c | 8 ++--- drivers/pnp/support.c | 2 +- drivers/pnp/system.c | 2 +- lib/vsprintf.c | 55 ++++++++++++++++++---------------- 13 files changed, 114 insertions(+), 107 deletions(-) diff --git a/arch/ia64/pci/pci.c b/arch/ia64/pci/pci.c index 06413b827e97..df639db779f9 100644 --- a/arch/ia64/pci/pci.c +++ b/arch/ia64/pci/pci.c @@ -298,18 +298,19 @@ static __devinit acpi_status add_window(struct acpi_resource *res, void *data) window->offset = offset;
