[PATCH next] ASoC: cs35l56: Fix unsigned 'rv' comparison with zero in cs35l56_irq()

[Harshit Mogalapalli]

'rv' is of type unsigned int, which can never be less than zero.

	rv = pm_runtime_resume_and_get(cs35l56->dev);
	if (rv < 0) { // can never be true.
		...
	}

As pm_runtime_resume_and_get returns integers, change the type of 'rv'
to int to fix this.

This is found by static analysis with smatch.
