If that happens\nfor a matching table entry, the resource lookup still returns success and\nthe following trylock dereferences a NULL mutex pointer while opening the\nresource.\n\nnfp_resource_acquire() already treats failure to allocate the table mutex\nas -ENOMEM.  Do the same for the resource mutex and fail the lookup before\npublishing the rest of the resource handle.\n\nThis issue was found by a static analysis checker and confirmed by\nmanual source review."
