From: Yang Li <redacted> [ Upstream commit 319f83ac98d7afaabab84ce5281a819a358b9895 ] When the value of nm->isr_ctx is false, the value of ret is 0. So, we set ret to -ENOMEM to indicate this error. Clean up smatch warning: drivers/ntb/test/ntb_msi_test.c:373 ntb_msit_probe() warn: missing error code 'ret'.
