[PATCH 5.4 145/475] ASoC: wm8350: Handle error for wm8350_register_irq

[Greg Kroah-Hartman]

From: Jiasheng Jiang <jiasheng@xxxxxxxxxxx>

[ Upstream commit db0350da8084ad549bca16cc0486c11cc70a1f9b ]

As the potential failure of the wm8350_register_irq(),
it should be better to check it and return error if fails.
Also, use 'free_' in order to avoid the same code.

Fixes: a6ba2b2dabb5 ("ASoC: Implement WM8350 headphone jack detection")
