Simply initializing the variables would result in "set but not used" warnings with W=1. Fix both types of warnings by making all the for_each macros unconditional and rely on the dummy static inline functions to initialize and reference any variables.

The of_bus_pci_match() function was looking only for "pci" on this property, so in such cases the bus matching code was falling back to the default bus, causing problems on functions that should be using "assigned-addresses" for region address translation. This patch fixes the problem by also looking for "pciex" on the PCI bus match function. v2: added comment Signed-off-by: Kleber Sacilotto de Souza Acked-by: Grant Likely Cc: stable@vger.kernel.org Signed-off-by: Rob Herring --- drivers/of/address.c | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) diff --git a/drivers/of/address.c b/drivers/of/address.c index d3dd41c840f1..1a54f1ffaadb 100644 --- a/drivers/of/address.c +++ b/drivers/of/address.c @@ -99,11 +99,12 @@ static unsigned int of_bus_default_get_flags(const __be32 *addr) static int of_bus_pci_match(struct device_node *np) { /* + * "pciex" is PCI Express * "vci" is for the /chaos bridge on 1st-gen PCI powermacs * "ht" is hypertransport */ - return !strcmp(np->type, "pci") || !strcmp(np->type, "vci") || - !strcmp(np->type, "ht"); + return !strcmp(np->type, "pci") || !strcmp(np->type, "pciex") || + !strcmp(np->type, "vci") || !strcmp(np->type, "ht"); } static void of_bus_pci_count_cells(struct device_node *np, -- cgit v1.2.3 From e066755163aaa4ae880a82d586e958051cf97c11 Mon Sep 17 00:00:00 2001 From: Heiko Stuebner Date: Thu, 30 Jan 2014 15:18:46 +0100 Subject: dt-bindings: add vendor-prefix for neonode Neonode Inc. is the Manufacturer of the zforce infraread touchscreens used in a lot of ebook readers and supported by the zforce_ts driver.
