NAME
       spi_w8r16be - SPI synchronous 8 bit write followed by 16 bit big-endian read

SYNOPSIS
       ssize_t spi_w8r16be(struct spi_device * spi, u8 cmd);

ARGUMENTS
       spi
           device with which data will be exchanged

       cmd
           command to be written before data is read back

CONTEXT
       can sleep

DESCRIPTION
       This function is similar to spi_w8r16, with the exception that it will convert the read 16
       bit data word from big-endian to native endianness.

       Callable only from contexts that can sleep.

RETURN
       the (unsigned) sixteen bit number returned by the device in cpu endianness, or else a
       negative error code.
