Name
hsi_alloc_msg —
Allocate an HSI message
Synopsis
struct hsi_msg * hsi_alloc_msg ( | unsigned int nents, |
| | gfp_t flags); |
Arguments
nents
Number of memory entries
flags
Kernel allocation flags
Description
nents can be 0. This mainly makes sense for read transfer.
In that case, HSI drivers will call the complete callback when
there is data to be read without consuming it.
Return NULL on failure or a pointer to an hsi_msg on success.
