#     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: faaa357a55e0 ("printk: move printk sysctl to printk/sysctl.c")
