BUG: cpufreq_proc_read give prematures eof for /proc/cpufreq (in 2.4.x-ac and 2.5)

[Ricardo Galli]

If a process reads from /proc/cpufreq with a small buffer, i.e. count < 
len, the function return always eof because len is always zero if the 
offset is > 0:

static int cpufreq_proc_read (
    char            *page,
...
{
    char            *p = page;
...

    if (off != 0)
        goto end;
    ...

end:
    len = (p - page);

where p = page.

Is this bug intentional to avoid overload or it's really a mistake?

PS: there is an obvious fix, I didn't attached to avoid you flaming me.
