Subject: drivers/media/usb/usbvision/usbvision-i2c.c: fix format overflow warning
gcc-7 notices that we copy a fixed length string into another
string of the same size, with additional characters:
drivers/media/usb/usbvision/usbvision-i2c.c: In function 'usbvision_i2c_register':
drivers/media/usb/usbvision/usbvision-i2c.c:190:36: error: '%d' directive writing between 1 and 11 bytes into a region of size between 0 and 47 [-Werror=format-overflow=]
sprintf(usbvision->i2c_adap.name, "%s-%d-%s", i2c_adap_template.name,
^~~~~~~~~~
drivers/media/usb/usbvision/usbvision-i2c.c:190:2: note: 'sprintf' output between 4 and 76 bytes into a destination of size 48
We know this is fine as the template name is always "usbvision", so
we can easily avoid the warning by using this as the format string
directly.
