[PATCH 0/5] usb: dwc2: Various fixes

Hi Felipe, These are some various patches for dwc2 for next. Thanks, John John Youn (1): usb: dwc2: Proper cleanup on dr_mode failure Sevak Arakelyan (1): usb: dwc2: Fixed SOF interrupt enabling/disabling Vahram Aharonyan (1): usb: dwc2: gadget: Check for ep0 in enable Vardan Mikayelyan

[PATCH 3/5] usb: dwc2: host: Setting qtd to NULL after freeing it

From: Vardan Mikayelyan This is safety change added while doing slub debugging. Affected functions: dwc2_hcd_qtd_unlink_and_free() _dwc2_hcd_urb_enqueue() Signed-off-by: Vardan Mikayelyan Signed-off-by: John Youn --- drivers/usb/dwc2/hcd.c | 1 + drivers/usb/dwc2/hcd.h | 1 + 2 files changed

[PATCH 4/5] usb: dwc2: Fixed SOF interrupt enabling/disabling

From: Sevak Arakelyan In case of DDMA mode we don't need to get an SOF interrupt so disable the unmasking of SOF interrupt in DDMA mode. Signed-off-by: Sevak Arakelyan Signed-off-by: John Youn --- drivers/usb/dwc2/hcd_queue.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git

[PATCH 2/5] usb: dwc2: gadget: Prevent handling of host interrupts

From: Vardan Mikayelyan In host slave mode, the core asserts the rxready, txfifoempty interrupts that get serviced in the gadget irq handler. Prevent servicing of these when not in the gadget mode of operation. Signed-off-by: Vardan Mikayelyan Signed-off-by: John Youn --- drivers/usb/dwc2/gad

[PATCH 5/5] usb: dwc2: Proper cleanup on dr_mode failure

Cleanup in probe if we fail to get dr_mode. Signed-off-by: John Youn --- drivers/usb/dwc2/platform.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/usb/dwc2/platform.c b/drivers/usb/dwc2/platform.c index 88629be..fc6f525 100644 --- a/drivers/usb/dwc2/platform.c +++ b

[PATCH 1/5] usb: dwc2: gadget: Check for ep0 in enable

[PATCH v2 1/2] usb: core: buffer: avoid NULL pointer dereferrence

NULL pointer dereferrence will happen when class driver wants to allocate zero length buffer and pool_max[0] can't be used, so simply returns NULL in the case. Signed-off-by: Chunfeng Yun --- drivers/usb/core/buffer.c |3 +++ 1 file changed, 3 insertions(+) diff --git a/drivers/usb/core/buf

[PATCH v2 2/2] usb: misc: usbtest: fix error of urb allocation

urb allocation will fail when usbtest_alloc_urb() tries to allocate zero length buffer, but it doesn't need it in fact, so just skips buffer allocation in the case. Signed-off-by: Chunfeng Yun --- drivers/usb/misc/usbtest.c |3 +++ 1 file changed, 3 insertions(+) diff --git a/drivers/usb/mi
