[PATCH v4 12/27] drm/bridge: ti-sn65dsi86: Cleanup managing of drvdata

Douglas Anderson
2021-04-16T22:41:49Z

Let's:
- Set the drvdata as soon as it's allocated. This just sets up a
pointer so there's no downside here.
- Remove the useless call to i2c_set_clientdata() which is literally
the same thing as dev_set_drvdata().

No functional changes intended.
