Subject: staging: vt6656: rxtx.c endian correct wTimeStampOff
X-Git-Tag: upstream/snapshot3+hdmi~4473^2~118
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=f115e76aea7f318df8535c8218ecbc9986e6d05a;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git

staging: vt6656: rxtx.c endian correct wTimeStampOff

wTimeStampOff needs to be endian corrected

Create new function vnt_time_stamp_off to return little endian u16 value.

Private variable byPreambleType is common to all calling functions is included.

variable rate to set the desired rate.
