[PATCH] media: vivid: drop unused 'j' variable

[PATCH] media: vivid: drop unused 'j' variable

[Hans Verkuil]

In two places the 'j' index variable was set but never used.
Drop it.

This fixes two compiler warnings:

drivers/media/test-drivers/vivid/vivid-cec.c: In function ‘find_dest_adap’:
drivers/media/test-drivers/vivid/vivid-cec.c:26:25: warning: variable ‘j’ set but not used [-Wunused-but-set-variable=]
   26 |         unsigned int i, j;
      |                         ^
drivers/media/test-drivers/vivid/vivid-cec.c: In function ‘vivid_cec_bus_thread’:
drivers/media/test-drivers/vivid/vivid-cec.c:116:25: warning: variable ‘j’ set but not used [-Wunused-but-set-variable=]
  116 |         unsigned int i, j;
      |                         ^
