[PATCH 3.18 14/52] media: em28xx: Fix misplaced reset of dev->v4l::field_count

[Greg Kroah-Hartman]

3.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Ben Hutchings <ben@xxxxxxxxxxxxxxx>

The backport of commit afeaade90db4 "media: em28xx: make
v4l2-compliance happier by starting sequence on zero" added a
reset on em28xx_v4l2::field_count to em28xx_ctrl_notify(),
but it should be done in em28xx_start_analog_streaming().
