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/media/platform/blackfin/ppi.c | 2 ++ 1 file changed, 2 insertions(+) (limited to 'kernel/drivers/media/platform/blackfin') diff --git a/kernel/drivers/media/platform/blackfin/ppi.c b/kernel/drivers/media/platform/blackfin/ppi.c index cff63e511..b8f3d9fa6 100644 --- a/kernel/drivers/media/platform/blackfin/ppi.c +++ b/kernel/drivers/media/platform/blackfin/ppi.c @@ -214,6 +214,8 @@ static int ppi_set_params(struct ppi_if *ppi, struct ppi_params *params) if (params->dlen > 24 || params->dlen <= 0) return -EINVAL; pctrl = devm_pinctrl_get(ppi->dev); + if (IS_ERR(pctrl)) + return PTR_ERR(pctrl); pstate = pinctrl_lookup_state(pctrl, pin_state[(params->dlen + 7) / 8 - 1]); if (pinctrl_select_state(pctrl, pstate)) -- cgit 1.2.3-korg
