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/memstick/host/rtsx_usb_ms.c | 6 ++++++ 1 file changed, 6 insertions(+) (limited to 'kernel/drivers/memstick') diff --git a/kernel/drivers/memstick/host/rtsx_usb_ms.c b/kernel/drivers/memstick/host/rtsx_usb_ms.c index 1105db235..83bfb1659 100644 --- a/kernel/drivers/memstick/host/rtsx_usb_ms.c +++ b/kernel/drivers/memstick/host/rtsx_usb_ms.c @@ -524,6 +524,7 @@ static void rtsx_usb_ms_handle_req(struct work_struct *work) int rc; if (!host->req) { + pm_runtime_get_sync(ms_dev(host)); do { rc = memstick_next_req(msh, &host->req); dev_dbg(ms_dev(host), "next req %d\n", rc); @@ -544,6 +545,7 @@ static void rtsx_usb_ms_handle_req(struct work_struct *work) host->req->error); } } while (!rc); + pm_runtime_put(ms_dev(host)); } } @@ -570,6 +572,7 @@ static int rtsx_usb_ms_set_param(struct memstick_host *msh, dev_dbg(ms_dev(host), "%s: param = %d, value = %d\n", __func__, param, value); + pm_runtime_get_sync(ms_dev(host)); mutex_lock(&ucr->dev_mutex); err = rtsx_usb_card_exclusive_check(ucr, RTSX_USB_MS_CARD); @@ -635,6 +638,7 @@ static int rtsx_usb_ms_set_param(struct memstick_host *msh, } out: mutex_unlock(&ucr->dev_mutex); + pm_runtime_put(ms_dev(host)); /* power-on delay */ if (param == MEMSTICK_POWER && value == MEMSTICK_POWER_ON) @@ -681,6 +685,7 @@ static int rtsx_usb_detect_ms_card(void *__host) int err; for (;;) { + pm_runtime_get_sync(ms_dev(host)); mutex_lock(&ucr->dev_mutex); /* Check pending MS card changes */ @@ -703,6 +708,7 @@ static int rtsx_usb_detect_ms_card(void *__host) } poll_again: + pm_runtime_put(ms_dev(host)); if (host->eject) break; -- cgit 1.2.3-korg
