From 52f993b8e89487ec9ee15a7fb4979e0f09a45b27 Mon Sep 17 00:00:00 2001 From: Yunhong Jiang Date: Wed, 8 Mar 2017 23:13:28 -0800 Subject: Upgrade to 4.4.50-rt62 The current kernel is based on rt kernel v4.4.6-rt14. We will upgrade it to 4.4.50-rt62. The command to achieve it is: a) Clone a git repo from git://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-stable-rt.git b) Get the diff between this two changesets: git diff 640eca2901f3435e616157b11379d3223a44b391 705619beeea1b0b48219a683fd1a901a86fdaf5e where the two commits are: [yjiang5@jnakajim-build linux-stable-rt]$ git show --oneline --name-only 640eca2901f3435e616157b11379d3223a44b391 640eca2901f3 v4.4.6-rt14 localversion-rt [yjiang5@jnakajim-build linux-stable-rt]$ git show --oneline --name-only 705619beeea1b0b48219a683fd1a901a86fdaf5e 705619beeea1 Linux 4.4.50-rt62 localversion-rt c) One patch has been backported thus revert the patch before applying. filterdiff -p1 -x scripts/package/Makefile ~/tmp/v4.4.6-rt14-4.4.50-rt62.diff |patch -p1 --dry-run Upstream status: backport Change-Id: I244d57a32f6066e5a5b9915f9fbf99e7bbca6e01 Signed-off-by: Yunhong Jiang --- kernel/drivers/usb/gadget/udc/dummy_hcd.c | 6 +++--- kernel/drivers/usb/gadget/udc/fsl_qe_udc.c | 9 +++------ kernel/drivers/usb/gadget/udc/udc-core.c | 2 +- 3 files changed, 7 insertions(+), 10 deletions(-) (limited to 'kernel/drivers/usb/gadget/udc') diff --git a/kernel/drivers/usb/gadget/udc/dummy_hcd.c b/kernel/drivers/usb/gadget/udc/dummy_hcd.c index dde44450d..22d067cd5 100644 --- a/kernel/drivers/usb/gadget/udc/dummy_hcd.c +++ b/kernel/drivers/usb/gadget/udc/dummy_hcd.c @@ -330,7 +330,7 @@ static void nuke(struct dummy *dum, struct dummy_ep *ep) /* caller must hold lock */ static void stop_activity(struct dummy *dum) { - struct dummy_ep *ep; + int i; /* prevent any more requests */ dum->address = 0; @@ -338,8 +338,8 @@ static void stop_activity(struct dummy *dum) /* The timer is left running so that outstanding URBs can fail */ /* nuke any pending requests first, so driver i/o is quiesced */ - list_for_each_entry(ep, &dum->gadget.ep_list, ep.ep_list) - nuke(dum, ep); + for (i = 0; i < DUMMY_ENDPOINTS; ++i) + nuke(dum, &dum->ep[i]); /* driver now does any non-usb quiescing necessary */ } diff --git a/kernel/drivers/usb/gadget/udc/fsl_qe_udc.c b/kernel/drivers/usb/gadget/udc/fsl_qe_udc.c index 5fb6f8b4f..b38a33584 100644 --- a/kernel/drivers/usb/gadget/udc/fsl_qe_udc.c +++ b/kernel/drivers/usb/gadget/udc/fsl_qe_udc.c @@ -1878,11 +1878,8 @@ static int qe_get_frame(struct usb_gadget *gadget) tmp = in_be16(&udc->usb_param->frame_n); if (tmp & 0x8000) - tmp = tmp & 0x07ff; - else - tmp = -EINVAL; - - return (int)tmp; + return tmp & 0x07ff; + return -EINVAL; } static int fsl_qe_start(struct usb_gadget *gadget, @@ -2053,7 +2050,7 @@ static void setup_received_handle(struct qe_udc *udc, struct qe_ep *ep; if (wValue != 0 || wLength != 0 - || pipe > USB_MAX_ENDPOINTS) + || pipe >= USB_MAX_ENDPOINTS) break; ep = &udc->eps[pipe]; diff --git a/kernel/drivers/usb/gadget/udc/udc-core.c b/kernel/drivers/usb/gadget/udc/udc-core.c index f660afba7..89f7cd66f 100644 --- a/kernel/drivers/usb/gadget/udc/udc-core.c +++ b/kernel/drivers/usb/gadget/udc/udc-core.c @@ -71,7 +71,7 @@ int usb_gadget_map_request(struct usb_gadget *gadget, mapped = dma_map_sg(dev, req->sg, req->num_sgs, is_in ?
