[Intel-wired-lan] [PATCH linux-next] iavf: Replace __FUNCTION__ with __func__

[Intel-wired-lan] [PATCH linux-next] iavf: Replace __FUNCTION__ with __func__

[yexingchen116]

From: ye xingchen <ye.xingchen@zte.com.cn>

__FUNCTION__ exists only for backwards compatibility reasons with old
gcc versions. Replace it with __func__.

yeah, how'd that sneak in there? Thanks!

Trivia: I suggest

		dev_warn(&adapter->pdev->dev, "%s: failed to acquire crit_lock\n", __func__);

As almost all printed uses of __func__ use a form like

	<printk_variant>("%s: message\n", __func__);

not

	<printk_variant>("message in %s\n", __func__);

I agree with Joe. Please fix this message up to use "%s: ...", __func__.
While at it, you might mention this fixes commit 226d528512cf ("iavf:
fix locking of critical sections") which introduced the use of __FUNCTION__.

Thanks,
