NAME

6       hsi_alloc_msg - Allocate an HSI message
7

SYNOPSIS

9       struct hsi_msg * hsi_alloc_msg(unsigned int nents, gfp_t flags);
10

ARGUMENTS

12       nents
13           Number of memory entries
14
15       flags
16           Kernel allocation flags
17

DESCRIPTION

19       nents can be 0. This mainly makes sense for read transfer. In that
20       case, HSI drivers will call the complete callback when there is data to
21       be read without consuming it.
22
23       Return NULL on failure or a pointer to an hsi_msg on success.
