[PATCH -next] usb: renesas_usbhs: gadget: fix return value check in usbhs_mod_gadget_probe()

In case of error, the function usb_get_phy() returns ERR_PTR() and never returns NULL. The NULL test in the return value check should be replaced with IS_ERR(). Signed-off-by: Wei Yongjun --- drivers/usb/renesas_usbhs/mod_gadget.c | 2 +- 1 file changed, 1 insertion(+), 1

[PATCH 2/2] usb: gadget: net2280: match interrupt endpoints to PIO endpoints and DMA to bulk

With composite gadget (ACM + NCM), USB3380 to host TCP transfer speed dropped to 150 Mbit/s compared to 900 Mbit/s with NCM gadget. Problem seems to be that net2280/USB3380 has only four DMA channels and those DMA channels are allocated to first HW endpoints. Endpoint match function was mapping

Gadgetfs - adding support for delegation of setup requests

Hi, I'm using GadgetFs for USB host fuzzing (using umap2), and part of the fuzzing session is to send invalid descriptors at various stages. However, some requests are not delegated to user-land (see gadgetfs_setup() in gadget/legacy/inode.c), Specifically - GET_DESCRIPTOR (device/configuration)

[PATCH 1/2] usb: gadget: net2280: fix infinite loop in irq handler
