[PATCH 3.16 185/202] [media] media: em28xx-dvb - fix em28xx_dvb_resume() to not unregister i2c and dvb

[Ben Hutchings]

3.16.66-rc1 review patch.  If anyone has any objections, please let me know.

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

From: Shuah Khan <shuah.kh@xxxxxxxxxxx>

commit 6eb5e3399e8f45aa191ad21c0556bece8ea559f2 upstream.

em28xx_dvb_resume() unregisters i2c tuner, i2c demod, and dvb.
This erroneous cleanup results in i2c tuner, i2c demod, and dvb
devices unregistered and removed during resume. This error is a
result of merge conflict between two patches that went into 3.15.
