USB: serial: cp210x: fix GPIO in autosuspend

2019-03-10T06:17:21Z

commit 7b0b644b9aa2de5032db0f468fddca091d0b7b90 upstream. Current GPIO code in cp210x fails to take USB autosuspend into account, making it practically impossible to use GPIOs with autosuspend enabled without user configuration. Fix this like for ftdi_sio in a previous patch. Tested on a CP2102N.

usb: gadget: Potential NULL dereference on allocation error

2019-03-05T16:58:47Z

[ Upstream commit df28169e1538e4a8bcd8b779b043e5aa6524545c ] The source_sink_alloc_func() function is supposed to return error pointers on error. The function is called from usb_get_function() which doesn't check for NULL returns so it would result in an Oops. Of course, in the current kernel, small allocations always succeed so this doesn't affect runtime. Signed-off-by: Dan Carpenter Signed-off-by: Felipe Balbi Signed-off-by: Sasha Levin

usb: dwc3: gadget: Fix the uninitialized link_state when udc starts

usb: gadget: musb: fix short isoc packets with inventra dma

2019-02-12T18:47:25Z

commit c418fd6c01fbc5516a2cd1eaf1df1ec86869028a upstream. Handling short packets (length < max packet size) in the Inventra DMA engine in the MUSB driver causes the MUSB DMA controller to hang. An example of a problem that is caused by this problem is when streaming video out of a UVC gadget, only the first video frame is transferred. For short packets (mode-0 or mode-1 DMA), MUSB_TXCSR_TXPKTRDY must be set manually by the driver. This was previously done in musb_g_tx (musb_gadget.c), but incorrectly (all csr flags were cleared, and only MUSB_TXCSR_MODE and MUSB_TXCSR_TXPKTRDY were set). Fixing that problem allows some requests to be transferred correctly, but multiple requests were often put together in one USB packet, and caused problems if the packet size was not a multiple of 4. Instead, set MUSB_TXCSR_TXPKTRDY in dma_controller_irq (musbhsdma.c), just like host mode transfers. This topic was originally tackled by Nicolas Boichat [0] [1] and is discussed further at [2] as part of his GSoC project [3].

usb: gadget: udc: net2272: Fix bitwise and boolean operations

2019-02-12T18:47:25Z

commit 07c69f1148da7de3978686d3af9263325d9d60bd upstream. (!x & y) strikes again. Fix bitwise and boolean operations by enclosing the expression: intcsr & (1 << NET2272_PCI_IRQ) in parentheses, before applying the boolean operator '!'. Notice that this code has been there since 2011. So, it would be helpful if someone can double-check this. This issue was detected with the help of Coccinelle.
