[PATCH] parport : "dev->timeslice" is an unsigned long, not an int

[Eric Dumazet]

While auditing proc_doulongvec_ms_jiffies_minmax() usage in kernel, I 
found a bug
in drivers/parport/procfs.c, incorrectly using sizeof(int) instead of 
sizeof(unsigned long)

Only 64bit arches are affected by this old bug.
