2015-01-15gpio: grgpio: off by one in grgpio_to_irq()Dan Carpenter
"gc->ngpio" is a number between 1 and GRGPIO_MAX_NGPIO. If "offset" is GRGPIO_MAX_NGPIO then we're going one step beyond the end of the priv->lirqs[] array.

2015-01-08gpio: grgpio: Avoid potential NULL pointer dereferenceAxel Lin
irqmap is optional property, so priv->domain can be NULL if !irqmap. Thus add NULL test for priv->domain before calling irq_domain_remove() to prevent NULL pointer dereference. Signed-off-by: Axel Lin <axel.lin@ingics.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core Pull driver core update from Greg KH: "Here's the set of driver core patches for 3.19-rc1. They are dominated by the removal of the .owner field in platform drivers. They touch a lot of files, but they are "simple" changes, just removing a line in a structure. Other than that, a few minor driver core and debugfs changes. There are some ath9k patches coming in through this tree that have been acked by the wireless maintainers as they relied on the debugfs changes. Everything has been in linux-next for a while" * tag 'driver-core-3.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: (324 commits) Revert "ath: ath9k: use debugfs_create_devm_seqfile() helper for seq_file entries" fs: debugfs: add forward declaration for struct device type firmware class: Deletion of an unnecessary check before the function call "vunmap" firmware loader: fix hung task warning dump devcoredump: provide a one-way disable function device: Add dev_<level>_once variants ath: ath9k: use debugfs_create_devm_seqfile() helper for seq_file entries ath: use seq_file api for ath9k debugfs files debugfs: add helper function to create device related seq_file drivers/base: cacheinfo: remove noisy error boot message Revert "core: platform: add warning if driver has no owner" drivers: base: support cpu cache information interface to userspace via sysfs drivers: base: add cpu_device_create to support per-cpu devices topology: replace custom attribute macros with standard DEVICE_ATTR* cpumask: factor out show_cpumap into separate helper function driver core: Fix unbalanced device reference in drivers_probe driver core: fix race with userland in device_add() sysfs/kernfs: make read requests on pre-alloc files use the buffer. sysfs/kernfs: allow attributes to request write buffer be pre-allocated. fs: sysfs: return EGBIG on write if offset is larger than file size ...

2013-04-26gpio: grgpio: Add irq supportAndreas Larsson
The drivers sets up an irq domain and hands out unique irqs to irq capable gpio lines regardless of how underlying irq maps to gpio lines. Any gpio line can map to any one or none of the irqs of the core, independently of each other.
