But if devm_add_action() fails then it will execute the action mentioned and return the error code. Signed-off-by: Sudip Mukherjee --- Next patch of the series will use this helper. And from a first glance more use of this helper will be there. include/linux/device.h | 12 ++++++++++++ 1 file changed, 12 insertions(+) diff --git a/include/linux/device.h b/include/linux/device.h index f627ba2..f2455d0 100644 --- a/include/linux/device.h +++ b/include/linux/device.h @@ -682,6 +682,18 @@ void __iomem *devm_ioremap_resource(struct device *dev, struct resource *res); int devm_add_action(struct device *dev, void (*action)(void *), void *data); void devm_remove_action(struct device *dev, void (*action)(void *), void *data); +static inline int devm_add_action_or_reset(struct device *dev, + void (*action)(void *), void *data) +{ + int ret; + + ret = devm_add_action(dev, action, data); + if (ret) + action(data); + + return ret; +} + struct device_dma_parameters { /* * a low level driver may set these to teach IOMMU code about -- 1.9.1
