From f42706c90470851fd2e97eda7a4109e8949bde8a Mon Sep 17 00:00:00 2001 From: Martin Fuzzey Date: Fri, 1 May 2009 17:21:11 +0200 Subject: USB: atmel-usba-udc : fix control out requests. usbtest #14 was failing with "udc: ep0: TXCOMP: Invalid endpoint state 2, halting endpoint..." This occured since ep0 is bidirectional and ep->is_in is not valid (must always use ep->state) Signed-off-by: Martin Fuzzey Acked-by: David Brownell Acked-by: Haavard Skinnemoen Signed-off-by: Greg Kroah-Hartman --- drivers/usb/gadget/atmel_usba_udc.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'drivers/usb/gadget') diff --git a/drivers/usb/gadget/atmel_usba_udc.c b/drivers/usb/gadget/atmel_usba_udc.c index 563d5727544..5644897c1c5 100644 --- a/drivers/usb/gadget/atmel_usba_udc.c +++ b/drivers/usb/gadget/atmel_usba_udc.c @@ -794,7 +794,8 @@ usba_ep_queue(struct usb_ep *_ep, struct usb_request *_req, gfp_t gfp_flags) if (ep->desc) { list_add_tail(&req->queue, &ep->queue); - if (ep->is_in || (ep_is_control(ep) + if ((!ep_is_control(ep) && ep->is_in) || + (ep_is_control(ep) && (ep->state == DATA_STAGE_IN || ep->state == STATUS_STAGE_IN))) usba_ep_writel(ep, CTL_ENB, USBA_TX_PK_RDY); -- cgit v1.2.3-18-g5258 From fe92c9e481a147a9e1e14f55870f32903b967777 Mon Sep 17 00:00:00 2001 From: Haavard Skinnemoen Date: Mon, 4 May 2009 17:22:43 -0700 Subject: USB: atmel_usb_udc: Use kzalloc() to allocate ep structures This ensures that all fields are properly initialized.
