patch "usb: gadget: musb: fix short isoc packets with inventra dma" added to usb-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled usb: gadget: musb: fix short isoc packets with inventra dma to my usb git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git in the usb-linus branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will hopefully also be merged in Linus's tree for the next -rc kernel release. If you have any questions about this process, please let me know. >From c418fd6c01fbc5516a2cd1eaf1df1ec86869028a Mon Sep 17 00:00:00 2001 From: Paul Elder <paul.elder(a)ideasonboard.com> Date: Wed, 30 Jan 2019 08:13:21 -0600 Subject: usb: gadget: musb: fix short isoc packets with inventra dma 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].

patch "serial: sh-sci: Do not free irqs that have already been freed" added to tty-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled serial: sh-sci: Do not free irqs that have already been freed to my tty git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty.git in the tty-linus branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will hopefully also be merged in Linus's tree for the next -rc kernel release. If you have any questions about this process, please let me know. >From 4d95987a32db53f3beca76f8c4c8309ef6a5f192 Mon Sep 17 00:00:00 2001 From: Chris Brandt <chris.brandt(a)renesas.com> Date: Mon, 28 Jan 2019 13:25:56 -0500 Subject: serial: sh-sci: Do not free irqs that have already been freed Since IRQs might be muxed on some parts, we need to pay attention when we are freeing them. Otherwise we get the ugly WARNING "Trying to free already-free IRQ 20".
