iio: proximity: pulsedlight v2: Tidy up an endian issue
Sparse identified the following CHECK drivers/iio/proximity/pulsedlight-lidar-lite-v2.c drivers/iio/proximity/pulsedlight-lidar-lite-v2.c:144:24: warning: cast to restricted __be16 drivers/iio/proximity/pulsedlight-lidar-lite-v2.c:144:24: warning: cast to restricted __be16 drivers/iio/proximity/pulsedlight-lidar-lite-v2.c:144:24: warning: cast to restricted __be16 drivers/iio/proximity/pulsedlight-lidar-lite-v2.c:144:24: warning: cast to restricted __be16 This cleans up by adding a local variable to hold the value whilst it is __be16 before applying endian converstion into eventual destination.
