[PATCH next] ice: Fix signedness bug in ice_init_interrupt_scheme()  

I believe it should be "PATCH net" with

If pci_alloc_irq_vectors() can't allocate the minimum number of vectors
then it returns -ENOSPC so there is no need to check for that in the
caller.  In fact, because pf->msix.min is an unsigned int, it means that
any negative error codes are type promoted to high positive values and
treated as success.  So here the "return -ENOMEM;" is unreachable code.
Check for negatives instead.

Fixes: 79d97b8cf9a8 ("ice: remove splitting MSI-X between features")  

a 'Stable:' tag here.

Bug only exists in net-next if it comes from commit under Fixes.
So I think the patch is good as is.
