Re: [PATCH] net: dsa: Delete an unnecessary check before the function call "put_device"

I'm starting to grow quite weary of these "unnecessary check" changes. Sometimes it is better to have them, either because the path is a hot path or some atomic sequence is involved. But there is never harm in them being there. All of this is a matter of taste, of course. But one thing I know

[PATCH] net: dsa: Delete an unnecessary check before the function call "put_device"

From: Markus Elfring Date: Sat, 14 Nov 2015 17:58:00 +0100 The put_device() function tests whether its argument is NULL and then returns immediately. Thus the test around the call is not needed. This issue was detected by using the Coccinelle software.
