struct fb_info* framebuffer_alloc ( size_t  size, struct device *  dev  )

read

framebuffer_alloc - creates a new frame buffer info structure

: size of driver private data, can be zero : pointer to the device for this fb, this can be NULL

Creates a new frame buffer info structure. Also reserves bytes for driver private data (info->par). info->par (if any) will be aligned to sizeof(long).

Returns the new structure, or NULL if an error occurred.

framebuffer_release - marks the structure available for freeing

: frame buffer info structure

Drop the reference count of the device embedded in the framebuffer info structure.
