[PATCH] ASoC: wm8350: Handle error for wm8350_register_irq
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.

I would probably just leave this as a return, nothing is gained changing it to a goto.
- ret = wm8350_register_irq(wm8350, WM8350_IRQ_CODEC_JCK_DET_R, wm8350_hpr_jack_handler, 0, "Right jack detect", priv);
- wm8350_register_irq(wm8350, WM8350_IRQ_CODEC_MICSCD,
- if (ret != 0)
goto free_JCK_DET_L;
Probably better to use non-caps here, having caps in a label is a little unusual.
Otherwise I think this looks fine.
Thanks, Charles
