Subject: [media] v4l2-mc: remove the unused sensor var Author: Mauro Carvalho Chehab <[email protected]> Date: Fri Feb 12 08:07:59 2016 -0200 This fixes this warning: v4l2-mc.c: In function 'v4l2_mc_create_media_graph': v4l2-mc.c:60:69: warning: variable 'sensor' set but not used [-Wunused-but-set-variable] We could solve it the other way: don't do the second loop for webcams. However, that would fail if a chip would have two sensors plugged. This is not the current case, but it doesn't hurt to be future-safe here, specially since this code runs only once during device probe. So, performance is not an issue here.
