ipc: adjust proc_ipc_sem_dointvec definition to match prototype
Commit 32927393dc1c ("sysctl: pass kernel pointers to ->proc_handler") changed ctl_table.proc_handler to take a kernel pointer. Adjust the signature of proc_ipc_sem_dointvec to match ctl_table.proc_handler which fixes the following sparse error/warning: ipc/ipc_sysctl.c:94:47: warning: incorrect type in argument 3 (different address spaces) ipc/ipc_sysctl.c:94:47: expected void *buffer ipc/ipc_sysctl.c:94:47: got void [noderef] __user *buffer ipc/ipc_sysctl.c:194:35: warning: incorrect type in initializer (incompatible argument 3 (different address spaces)) ipc/ipc_sysctl.c:194:35: expected int ( [usertype] *proc_handler )( ... ) ipc/ipc_sysctl.c:194:35: got int ( * )( ... ) Fixes: 32927393dc1c ("sysctl: pass kernel pointers to ->proc_handler") Signed-off-by: Tobias Klauser <> Signed-off-by: Andrew Morton <> Cc: Christoph Hellwig <> Cc: Alexander Viro <> Link: Signed-off-by: Linus Torvalds <>
