kernel/hung_task: fix address space of proc_dohung_task_timeout_secs
The proc_dohung_task_timeout_secs() function is incorrectly marked
as having a __user buffer as argument 3. However this is not the
case and it is casing multiple sparse warnings. Fix the following
warnings by removing __user from the argument:
kernel/hung_task.c:237:52: warning: incorrect type in argument 3 (different address spaces)
kernel/hung_task.c:237:52: expected void *
kernel/hung_task.c:237:52: got void [noderef] __user *buffer
kernel/hung_task.c:287:35: warning: incorrect type in initializer (incompatible argument 3 (different address spaces))
kernel/hung_task.c:287:35: expected int ( [usertype] *proc_handler )( ... )
kernel/hung_task.c:287:35: got int ( * )( ... )
kernel/hung_task.c:295:35: warning: incorrect type in initializer (incompatible argument 3 (different address spaces))
kernel/hung_task.c:295:35: expected int ( [usertype] *proc_handler )( ... )
kernel/hung_task.c:295:35: got int ( * )( ... )
