[uml-devel] [PATCH 1/2] um: vector: Fix a memory allocation check

[Christophe J. <chr...@wa...>]

Checking the result of the previous 'kstrdup()' call is expected here, so
we should test 'params' and not 'str' (which is known to be non-NULL at
this point)

Fixes: ad1f62ab2bd4 ("High Performance UML Vector Network Driver")
