[PATCH v9 02/14] usb: otg-fsm: Prevent build warning "VDBG" redefined
From: Roger Quadros <hidden>

If usb/otg-fsm.h and usb/composite.h are included together then it results in the build warning [1]. Prevent that by defining VDBG locally. Also get rid of MPC_LOC which doesn't seem to be used by anyone. [1] - warning fixed by this patch: In file included from drivers/usb/dwc3/core.h:33, from drivers/usb/dwc3/ep0.c:33: include/linux/usb/otg-fsm.h:30:1: warning: "VDBG" redefined In file included from drivers/usb/dwc3/ep0.c:31: include/linux/usb/composite.h:615:1: warning: this is the location of the previous definition Signed-off-by: Roger Quadros <redacted> Acked-by: Peter Chen <redacted> --- drivers/usb/common/usb-otg-fsm.c | 7 +++++++ drivers/usb/phy/phy-fsl-usb.c | 7 +++++++ include/linux/usb/otg-fsm.h | 15 --------------- 3 files changed, 14 insertions(+), 15 deletions(-)
