Subject: [PATCH] video: fbdev: core: fbmon.c: Cleaning up useless assignment of function parameter

Remove assignment of function parameter, that has no effect outside the function

This was found using a static code analysis program called cppcheck

I guess the intention was:

memset(specs, 0, sizeof(struct fb_monspecs));

Hi Geert!

Yeah, maybe. Just looks to be a little too elementary mistake..?

But do you want me to change it to that?

With a:
if(specs)
memset()

maybe..?


Kind regards
