Subject: [PATCH v4 04/11] staging: r8188eu: use htons macro instead of
__constant_htons
Macro "htons" is more efficient and clearer. It should be used for
constants instead of the __constant_htons macro. Resolves following
checkpatch script complaint:
WARNING: __constant_htons should be htons
Signed-off-by: Deepak R Varma <drv@...lo.com>

Changes in v4:
-- None.
Changes in v3:
1. Make this a driver-wide change. Feedback from philipp.g.hortmann@...il.com
2. Correct spelling in patch log. Feedback from joe@...ches.com
