HSI_ALLOC_MSG(9)                  High Speed Synchronous Serial                  HSI_ALLOC_MSG(9)



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.
