NAME¶
hsi_alloc_msg - Allocate an HSI messageSYNOPSIS¶
struct
hsi_msg * hsi_alloc_msg(unsigned int nents,
gfp_t flags);
ARGUMENTS¶
nentsNumber 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.COPYRIGHT¶
