[lvc-project] [PATCH] ASoC: simple-card-utils: Fix error handling in simple_util_init_jack()

[Igor Artemiev]

Currently, if snd_soc_card_jack_new_pins() or snd_soc_jack_add_gpios()
fails, the function continues execution without handling the error.
This can lead to unexpected behavior and potential crashes.

This patch fixes the problem by checking the return value 
of these functions.

Found by Linux Verification Center (linuxtesting.org) with SVACE.
