Subject: [PATCH v2] ASoC: wm8350: Handle error for wm8350_register_irq
Date: Fri,  4 Mar 2022 10:38:21 +0800	[thread overview]
Message-ID: <20220304023821.391936-1-jiasheng@iscas.ac.cn> (raw)

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")
Signed-off-by: Jiasheng Jiang <jiasheng@iscas.ac.cn>
---
Changelog:

v1 -> v2

* Change 1. Change to non-caps labels and remove the revert to 'return ret;'.
