struct platform_device question

[whiskbroom]

Hello:

Couple questions, would appreciate any help:

#1: In the construct below, what is the result of the single "#" that precedes _name below:

#define DEFINE_DEV(_name, _id) \
static u64 _name##_id##_dma_mask = DMA_32BIT_MASK; \
static struct platform_device _name##_id##_device = { \
.name = #_name, \
.id = _id, \
.dev = { \
.dma_mask = &_name##_id##_dma_mask, \
.coherent_dma_mask = DMA_32BIT_MASK, \
}, \
.resource = _name##_id##_resource, \
.num_resources = ARRAY_SIZE(_name##_id##_resource), \
}


#2: Is the string value pointed to by the .name field in struct platform_device, the string value that should be used in the .name field of struct platform_driver when calling the platform_driver_probe() function?

Thanks!

Yes, the string value pointed to by .name in platform_device structure and in platform_driver structure should be same....
