Subject: [PATCH 3/3] staging:iio:ade7753/ade7754/ade7759: Use spi_w8r16be() instead of spi_w8r16()
Using spi_w8r16be() will do the conversion of the result from big endian to
native endian in the helper function. This makes the code a bit smaller and also
keeps sparse happy. Fixes the following sparse warnings:
drivers/staging/iio/meter/ade7753.c:97:29: warning: incorrect type in argument 1 (different base types)
