1. NAME

hsi_alloc_msg - Allocate an HSI message

2. SYNOPSIS

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

3. ARGUMENTS

nents
    Number of memory entries

flags
    Kernel allocation flags

4. 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.
