iio:adc:ti-adc084s021 Tidy up endian types
By adding a few local variables and avoiding a void * for a parameter we can easily make all the endian types explicit and get rid of the warnings from sparse: CHECK drivers/iio/adc/ti-adc084s021.c drivers/iio/adc/ti-adc084s021.c:84:26: warning: incorrect type in assignment (different base types) drivers/iio/adc/ti-adc084s021.c:84:26: expected unsigned short [usertype] drivers/iio/adc/ti-adc084s021.c:84:26: got restricted __be16 drivers/iio/adc/ti-adc084s021.c:115:24: warning: cast to restricted __be16 drivers/iio/adc/ti-adc084s021.c:115:24: warning: cast to restricted __be16 drivers/iio/adc/ti-adc084s021.c:115:24: warning: cast to restricted __be16 drivers/iio/adc/ti-adc084s021.c:115:24: warning: cast to restricted __be16 Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com> Reviewed-by: Andy Shevchenko <andy.shevchenko@gmail.com> Link: https://lore.kernel.org/r/20200722155103.979802-23-jic23@kernel.org
