Subject: [PATCH 4.2.y-ckt 202/268] ASoC: tegra_alc5632: check return value

4.2.8-ckt3 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Sudip Mukherjee <sudipm.mukherjee@...il.com>

commit 319c32597fc22a58b946a6146f2be1fd208582e0 upstream.

We have been returning success even if snd_soc_card_jack_new() fails.
Lets check the return value and return error if it fails.

Fixes: 12cc6d1dca4d ("ASoC: tegra_alc5632: Register jacks at the card level")
