SPI_RES_ALLOC(9)                  Serial Peripheral Interface (S                 SPI_RES_ALLOC(9)



NAME
       spi_res_alloc - allocate a spi resource that is life-cycle managed during the processing
       of a spi_message while using spi_transfer_one

SYNOPSIS
       void * spi_res_alloc(struct spi_device * spi, spi_res_release_t release, size_t size,
                            gfp_t gfp);

ARGUMENTS
       spi
           the spi device for which we allocate memory

       release
           the release code to execute for this resource

       size
           size to alloc and return

       gfp
           GFP allocation flags

RETURN
       the pointer to the allocated data

       This may get enhanced in the future to allocate from a memory pool of the spi_device or
       spi_master to avoid repeated allocations.
