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/mtd/maps/pmcmsp-flash.c | 6 +++--- kernel/drivers/mtd/maps/sa1100-flash.c | 4 +++- 2 files changed, 6 insertions(+), 4 deletions(-) (limited to 'kernel/drivers/mtd/maps') diff --git a/kernel/drivers/mtd/maps/pmcmsp-flash.c b/kernel/drivers/mtd/maps/pmcmsp-flash.c index 744ca5cac..f9fa3fad7 100644 --- a/kernel/drivers/mtd/maps/pmcmsp-flash.c +++ b/kernel/drivers/mtd/maps/pmcmsp-flash.c @@ -75,15 +75,15 @@ static int __init init_msp_flash(void) printk(KERN_NOTICE "Found %d PMC flash devices\n", fcnt); - msp_flash = kmalloc(fcnt * sizeof(struct map_info *), GFP_KERNEL); + msp_flash = kcalloc(fcnt, sizeof(*msp_flash), GFP_KERNEL); if (!msp_flash) return -ENOMEM; - msp_parts = kmalloc(fcnt * sizeof(struct mtd_partition *), GFP_KERNEL); + msp_parts = kcalloc(fcnt, sizeof(*msp_parts), GFP_KERNEL); if (!msp_parts) goto free_msp_flash; - msp_maps = kcalloc(fcnt, sizeof(struct mtd_info), GFP_KERNEL); + msp_maps = kcalloc(fcnt, sizeof(*msp_maps), GFP_KERNEL); if (!msp_maps) goto free_msp_parts; diff --git a/kernel/drivers/mtd/maps/sa1100-flash.c b/kernel/drivers/mtd/maps/sa1100-flash.c index 142fc3d79..784c6e1a0 100644 --- a/kernel/drivers/mtd/maps/sa1100-flash.c +++ b/kernel/drivers/mtd/maps/sa1100-flash.c @@ -230,8 +230,10 @@ static struct sa_info *sa1100_setup_mtd(struct platform_device *pdev, info->mtd = mtd_concat_create(cdev, info->num_subdev, plat->name); - if (info->mtd == NULL) + if (info->mtd == NULL) { ret = -ENXIO; + goto err; + } } info->mtd->dev.parent = &pdev->dev; -- cgit 1.2.3-korg
