Subject: mlx4_core: Fix memory leak in mlx4_enable_msi_x()
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=5bf0da7dd0ae193e072412519cba1d77b6196c61;p=deliverable%2Flinux.git

mlx4_core: Fix memory leak in mlx4_enable_msi_x()

When the msi_x option is enabled but pci_enable_msix() fails (not
enough vectors are available etc), the entries array was not freed on
the error path.
