From 5c2a18014f906d81ae83484801831650f0fa07fe Mon Sep 17 00:00:00 2001 From: Oliver Neukum Date: Mon, 18 Nov 2013 13:22:57 +0100 Subject: [PATCH] ohci: remove conditional compilation Conditional compilation for debugging is removed in favor of dynamic debugging. To do so 1. the support for debugfs is always compiled 2. the support for the ancient print_urb debugging aid is removed Signed-off-by: Oliver Neukum Signed-off-by: Greg Kroah-Hartman --- drivers/usb/host/ohci-dbg.c | 69 ------------------------------------- drivers/usb/host/ohci-hcd.c | 8 ----- drivers/usb/host/ohci-q.c | 4 --- drivers/usb/host/ohci.h | 7 +--- 4 files changed, 1 insertion(+), 87 deletions(-) diff --git a/drivers/usb/host/ohci-dbg.c b/drivers/usb/host/ohci-dbg.c index 3fca52ec02a..45032e933e1 100644 --- a/drivers/usb/host/ohci-dbg.c +++ b/drivers/usb/host/ohci-dbg.c @@ -9,8 +9,6 @@ /*-------------------------------------------------------------------------*/ -#ifdef DEBUG - #define edstring(ed_type) ({ char *temp; \ switch (ed_type) { \ case PIPE_CONTROL: temp = "ctrl"; break; \ @@ -20,57 +18,6 @@ } temp;}) #define pipestring(pipe) edstring(usb_pipetype(pipe)) -/* debug| print the main components of an URB - * small: 0) header + data packets 1) just header - */ -static void __maybe_unused -urb_print(struct urb * urb, char * str, int small, int status) -{ - unsigned int pipe= urb->pipe; - - if (!urb->dev || !urb->dev->bus) { - printk(KERN_DEBUG "%s URB: no dev\n", str); - return; - } - -#ifndef OHCI_VERBOSE_DEBUG - if (status != 0) -#endif - printk(KERN_DEBUG "%s %p dev=%d ep=%d%s-%s flags=%x len=%d/%d stat=%d\n", - str, - urb, - usb_pipedevice (pipe), - usb_pipeendpoint (pipe), - usb_pipeout (pipe)?
