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 ( * )( ... ) Link: https://lkml.kernel.org/r/20220714074744.189017-1-ben.dooks@sifive.com Signed-off-by: Ben Dooks <ben.dooks@sifive.com> Cc: <Conor.Dooley@microchip.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org>
