From: "Ben Dooks (Codethink)" <ben.dooks@xxxxxxxxxxxxxxx> The trace functions should have __iomem on the addr pointers. Add __iomem to avoid the following warnings from sparse: drivers/usb/musb/musb_core.c:253:55: warning: incorrect type in argument 2 (different address spaces) drivers/usb/musb/musb_core.c:253:55: expected void const *addr drivers/usb/musb/musb_core.c:253:55: got void const [noderef] <asn:2> *addr drivers/usb/musb/musb_core.c:259:56: warning: incorrect type in argument 2 (different address spaces) drivers/usb/musb/musb_core.c:259:56: expected void const *addr drivers/usb/musb/musb_core.c:259:56: got void [noderef] <asn:2> *addr drivers/usb/musb/musb_core.c:267:55: warning: incorrect type in argument 2 (different address spaces) drivers/usb/musb/musb_core.c:267:55: expected void const *addr drivers/usb/musb/musb_core.c:267:55: got void const [noderef] <asn:2> *addr drivers/usb/musb/musb_core.c:273:56: warning: incorrect type in argument 2 (different address spaces) drivers/usb/musb/musb_core.c:273:56: expected void const *addr drivers/usb/musb/musb_core.c:273:56: got void [noderef] <asn:2> *addr drivers/usb/musb/musb_core.c:383:55: warning: incorrect type in argument 2 (different address spaces) drivers/usb/musb/musb_core.c:383:55: expected void const *addr drivers/usb/musb/musb_core.c:383:55: got void const [noderef] <asn:2> *addr drivers/usb/musb/musb_core.c:390:56: warning: incorrect type in argument 2 (different address spaces) drivers/usb/musb/musb_core.c:390:56: expected void const *addr drivers/usb/musb/musb_core.c:390:56: got void [noderef] <asn:2> *addr Signed-off-by: Ben Dooks (Codethink) <ben.dooks@xxxxxxxxxxxxxxx> Signed-off-by: Bin Liu <b-liu@xxxxxx> --- drivers/usb/musb/musb_trace.h | 33 +++++++++++++++++++++------------ 1 file changed, 21 insertions(+), 12 deletions(-) diff --git a/drivers/usb/musb/musb_trace.h b/drivers/usb/musb/musb_trace.h index a97d618fe8ff..b193daf69685 100644 --- a/drivers/usb/musb/musb_trace.h +++ b/drivers/usb/musb/musb_trace.h @@ -38,11 +38,12 @@ TRACE_EVENT(musb_log, ); DECLARE_EVENT_CLASS(musb_regb, - TP_PROTO(void *caller, const void *addr, unsigned int offset, u8 data), + TP_PROTO(void *caller, const void __iomem *addr, + unsigned int offset, u8 data), TP_ARGS(caller, addr, offset, data), TP_STRUCT__entry( __field(void *, caller) - __field(const void *, addr) + __field(const void __iomem *, addr) __field(unsigned int, offset) __field(u8, data) ), @@ -57,21 +58,24 @@ DECLARE_EVENT_CLASS(musb_regb, ); DEFINE_EVENT(musb_regb, musb_readb, - TP_PROTO(void *caller, const void *addr, unsigned int offset, u8 data), + TP_PROTO(void *caller, const void __iomem *addr, + unsigned int offset, u8 data), TP_ARGS(caller, addr, offset, data) ); DEFINE_EVENT(musb_regb, musb_writeb, - TP_PROTO(void *caller, const void *addr, unsigned int offset, u8 data), + TP_PROTO(void *caller, const void __iomem *addr, + unsigned int offset, u8 data), TP_ARGS(caller, addr, offset, data) ); DECLARE_EVENT_CLASS(musb_regw, - TP_PROTO(void *caller, const void *addr, unsigned int offset, u16 data), + TP_PROTO(void *caller, const void __iomem *addr, + unsigned int offset, u16 data), TP_ARGS(caller, addr, offset, data), TP_STRUCT__entry( __field(void *, caller) - __field(const void *, addr) + __field(const void __iomem *, addr) __field(unsigned int, offset) __field(u16, data) ), @@ -86,21 +90,24 @@ DECLARE_EVENT_CLASS(musb_regw, ); DEFINE_EVENT(musb_regw, musb_readw, - TP_PROTO(void *caller, const void *addr, unsigned int offset, u16 data), + TP_PROTO(void *caller, const void __iomem *addr, + unsigned int offset, u16 data), TP_ARGS(caller, addr, offset, data) ); DEFINE_EVENT(musb_regw, musb_writew, - TP_PROTO(void *caller, const void *addr, unsigned int offset, u16 data), + TP_PROTO(void *caller, const void __iomem *addr, + unsigned int offset, u16 data), TP_ARGS(caller, addr, offset, data) ); DECLARE_EVENT_CLASS(musb_regl, - TP_PROTO(void *caller, const void *addr, unsigned int offset, u32 data), + TP_PROTO(void *caller, const void __iomem *addr, + unsigned int offset, u32 data), TP_ARGS(caller, addr, offset, data), TP_STRUCT__entry( __field(void *, caller) - __field(const void *, addr) + __field(const void __iomem *, addr) __field(unsigned int, offset) __field(u32, data) ), @@ -115,12 +122,14 @@ DECLARE_EVENT_CLASS(musb_regl, ); DEFINE_EVENT(musb_regl, musb_readl, - TP_PROTO(void *caller, const void *addr, unsigned int offset, u32 data), + TP_PROTO(void *caller, const void __iomem *addr, + unsigned int offset, u32 data), TP_ARGS(caller, addr, offset, data) ); DEFINE_EVENT(musb_regl, musb_writel, - TP_PROTO(void *caller, const void *addr, unsigned int offset, u32 data), + TP_PROTO(void *caller, const void __iomem *addr, + unsigned int offset, u32 data), TP_ARGS(caller, addr, offset, data) ); -- 2.17.1
