From 1eb734fed3b79a5e6106dad16e88041894fdab30 Mon Sep 17 00:00:00 2001 From: Thomas Abraham Date: Sun, 4 Jan 2009 12:15:35 +0530 Subject: usb : usb_kbd : Populating 'priv' member of USB keyboard device_t structure This patch populates the 'priv' field of the USB keyboard device_t structure. The 'priv' field is populated with the address of the 'struct usb_device' structure that represents the USB device. The 'priv' field can then be used in the 'usb_event_poll' function to determine the USB device that requires to be polled. An example of its usage in 'usb_event_poll' function is as below. device_t *dev; struct usb_device *usb_kbd_dev; dev = device_get_by_name("usbkbd"); usb_kbd_dev = (struct usb_device *)dev->priv; iface = &usb_kbd_dev->config.if_desc[0]; Signed-off-by: Thomas Abraham Signed-off-by: Remy Bohmer --- common/usb_kbd.c | 1 + 1 file changed, 1 insertion(+) (limited to 'common') diff --git a/common/usb_kbd.c b/common/usb_kbd.c index 89e6ee7..e0d006c 100644 --- a/common/usb_kbd.c +++ b/common/usb_kbd.c @@ -183,6 +183,7 @@ int drv_usb_kbd_init(void) usb_kbd_dev.puts = NULL; usb_kbd_dev.getc = usb_kbd_getc; usb_kbd_dev.tstc = usb_kbd_testc; + usb_kbd_dev.priv = (void *)dev; error = device_register (&usb_kbd_dev); if(error==0) { /* check if this is the standard input device */ -- cgit v1.1
