gcc points out that the length of the temporary buffer may not be sufficient for
large numbers of leds:
drivers/net/phy/mscc.c: In function 'vsc85xx_probe':
drivers/net/phy/mscc.c:460:45: error: '-mode' directive writing 5 bytes into a region of size between 0 and 9 [-Werror=format-overflow=]
ret = sprintf(led_dt_prop, "vsc8531,led-%d-mode", i);
^~~~~
drivers/net/phy/mscc.c:460:9: note: 'sprintf' output between 19 and 28 bytes into a destination of size 22
ret = sprintf(led_dt_prop, "vsc8531,led-%d-mode", i);
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
While we can make a reasonable assumption that the number of LEDs is small,
the cost of making the buffer a little bigger is insignificant as well.
