Mickaël Salaün 1f2cfdd349 printk: Fix incorrect __user type in proc_dointvec_minmax_sysadmin() 
The move of proc_dointvec_minmax_sysadmin() from kernel/sysctl.c to
kernel/printk/sysctl.c introduced an incorrect __user attribute to the
buffer argument.  I spotted this change in [1] as well as the kernel
test robot.  Revert this change to please sparse:

  kernel/printk/sysctl.c:20:51: warning: incorrect type in argument 3 (different address spaces)
  kernel/printk/sysctl.c:20:51:    expected void *
  kernel/printk/sysctl.c:20:51:    got void [noderef] __user *buffer

Fixes: faaa357a55 ("printk: move printk sysctl to printk/sysctl.c")
