The compilation with CONFIG_WERROR=y is broken:

.../hw/mana/device.c:88:6: error: variable 'ret' is used uninitialized whenever 'if' condition is true [-Werror,-Wsometimes-uninitialized]
	if (!upper_ndev) {
	    ^~~~~~~~~~~

Fix this by assigning the ret to -ENODEV in respective condition.

Fixes: 8b184e4f1c32 ("RDMA/mana_ib: Enable RoCE on port 1")

Hmm... The below patch had been sent _after_ mine. What's wrong with mine patch?

It wasn't

Your's:
Date: Tue, 23 Apr 2024 23:42:58 +0300	[thread overview]

Konstantin's:
Date: Tue, 23 Apr 2024 07:15:51 -0700	[thread overview]

He beat you by 6 hours, which is why I took his, yours didn't exist at
the time I took it.
