DMA_BUF_ATTACH(9) Device drivers infrastructure DMA_BUF_ATTACH(9)NAME
dma_buf_attach - Add the device to dma_buf's attachments list; optionally, calls attach of dma_buf_ops to allow device-specific attach
functionality
SYNOPSIS
struct dma_buf_attachment * dma_buf_attach(struct dma_buf * dmabuf, struct device * dev);
ARGUMENTS
dmabuf
[in] buffer to attach device to.
dev
[in] device to be attached.
DESCRIPTION
Returns struct dma_buf_attachment * for this attachment; may return negative error codes.

DEVICE_CREATE_VARGS(9) Device drivers infrastructure DEVICE_CREATE_VARGS(9)NAME
device_create_vargs - creates a device and registers it with sysfs
SYNOPSIS
struct device * device_create_vargs(struct class * class, struct device * parent, dev_t devt, void * drvdata, const char * fmt,
va_list args);
ARGUMENTS
class
pointer to the struct class that this device should be registered to
parent
pointer to the parent struct device of this new device, if any
devt
the dev_t for the char device to be added
drvdata
the data to be added to the device for callbacks
fmt
string for the device's name
args
va_list for the device's name
DESCRIPTION
This function can be used by char device classes. A struct device will be created in sysfs, registered to the specified class.
A "dev" file will be created, showing the dev_t for the device, if the dev_t is not 0,0. If a pointer to a parent struct device is passed
in, the newly created struct device will be a child of that device in sysfs. The pointer to the struct device will be returned from the
call. Any further sysfs files that might be required can be created using this pointer.
Returns struct device pointer on success, or ERR_PTR on error.
NOTE
the struct class passed to this function must have previously been created with a call to class_create.
