That whole function looks a bit ... convoluted? How about this? I guess
you could trim it down even further, but this looks quite readable to me:

diff --git a/drivers/virt/nitro_enclaves/ne_misc_dev.c
b/drivers/virt/nitro_enclaves/ne_misc_dev.c
index f06622b48d69..5b7f45e2eb4c 100644
--- a/drivers/virt/nitro_enclaves/ne_misc_dev.c
+++ b/drivers/virt/nitro_enclaves/ne_misc_dev.c
@@ -1505,10 +1505,8 @@ static __poll_t ne_enclave_poll(struct file
*file, poll_table *wait)

poll_wait(file, &ne_enclave->eventq, wait);

- if (!ne_enclave->has_event)
- return mask;
-
- mask = POLLHUP;
+ if (ne_enclave->has_event)
+ mask |= POLLHUP;

return mask;
}
