This patch removes the unused variable 'val' from the __do_proc_dointvec() function in kernel/sysctl.h. The integer has been declared and used as 'val = -val' and there is no reference to it anywhere. Although I am this doesn't affects the kernel binary because gcc removes it, still it might be confusing for people reading the code.
