From b7fa5c2aec5be083eb2719b405089703608e9bc6 Mon Sep 17 00:00:00 2001 From: Felipe Balbi Date: Thu, 14 Mar 2013 17:59:06 +0200 Subject: [PATCH] usb: phy: return -ENXIO when PHY layer isn't enabled in cases where PHY layer isn't enabled, we want to still return an error code (actually an error pointer) so that our users don't need to cope with either error pointer of NULL. This will simplify users as below: - return IS_ERR(phy) ? PTR_ERR(phy) : -ENODEV; + return PTR_ERR(phy); Acked-by: Kishon Vijay Abraham I Reported-by: Alan Stern Signed-off-by: Felipe Balbi --- include/linux/usb/phy.h | 10 +++++----- 1 file changed, 5 insertions(+), 5 deletions(-) diff --git a/include/linux/usb/phy.h b/include/linux/usb/phy.h index b7c2217c585f..6b5978f57633 100644 --- a/include/linux/usb/phy.h +++ b/include/linux/usb/phy.h @@ -197,29 +197,29 @@ extern int usb_bind_phy(const char *dev_name, u8 index, #else static inline struct usb_phy *usb_get_phy(enum usb_phy_type type) { - return NULL; + return ERR_PTR(-ENXIO); } static inline struct usb_phy *devm_usb_get_phy(struct device *dev, enum usb_phy_type type) { - return NULL; + return ERR_PTR(-ENXIO); } static inline struct usb_phy *usb_get_phy_dev(struct device *dev, u8 index) { - return NULL; + return ERR_PTR(-ENXIO); } static inline struct usb_phy *devm_usb_get_phy_dev(struct device *dev, u8 index) { - return NULL; + return ERR_PTR(-ENXIO); } static inline struct usb_phy *devm_usb_get_phy_by_phandle(struct device *dev, const char *phandle, u8 index) { - return NULL; + return ERR_PTR(-ENXIO); } static inline void usb_put_phy(struct usb_phy *x) -- 2.20.1
