If you change the declaration of p from "char *p" into "const char *p"
you won't need a cast in the above for loop.

As far as I know sysfs doesn't terminate buf with a '\0' before calling
a store method. Does that mean that you are passing a string that is not
'\0'-terminated to a function that expects a '\0'-terminated string ?
