stackleak: let stack_erasing_sysctl take a kernel pointer buffer
Commit 32927393 ("sysctl: pass kernel pointers to ->proc_handler") changed ctl_table.proc_handler to take a kernel pointer. Adjust the signature of stack_erasing_sysctl to match ctl_table.proc_handler which fixes the following sparse warning: kernel/stackleak.c:31:50: warning: incorrect type in argument 3 (different address spaces) kernel/stackleak.c:31:50: expected void * kernel/stackleak.c:31:50: got void [noderef] __user *buffer Fixes: 32927393 ("sysctl: pass kernel pointers to ->proc_handler") Signed-off-by:Tobias Klauser <tklauser@distanz.ch> Signed-off-by:
