ASoC: soc-dapm.c: fixup snd_soc_dapm_new_control_unlocked() error handling

Browse source

Current snd_soc_dapm_new_control_unlocked() error handling is wrong.
It is using "goto request_failed" (A), but error message is using
"w->name" (B) which is not yet created in such timing.

	snd_soc_dapm_new_control_unlocked(xxx)
	{
		...
		switch (w->id) {
		case xxx:
			...
			if (IS_ERR(...)) {
				ret = PTR_ERR(...);
(A)				goto request_failed;
			}
		...
		}

		prefix = soc_dapm_prefix(...);
		if (prefix)
(B)			w->name = kasprintf(...);
		else
(B)			w->name = kstrdup_const(...);
		...

(A)	request_failed:
		if (ret != -EPROBE_DEFER)
(B)			dev_err(..., w->name, ...);

		return ...;
	}

we can create "w->name" at beginning of this function.
In such case, we need to call kfree_const(w->name) at error case.
This patch do these.
