Subject: [PATCH] [media] mxl111sf: remove redundant assignment to index

From: Colin Ian King <colin.king@...onical.com>

Variable index is set to zero and then set to zero again
a few lines later in a for loop initialization. Remove the
redundant setting of index to zero. Cleans up the clang
warning:

drivers/media/usb/dvb-usb-v2/mxl111sf-i2c.c:519:3: warning: Value
stored to 'index' is never read
