[dpdk-stable] [PATCH v3 3/5] raw/ifpga/base: fix return of IRQ unregister properly

[Tianfei zhang]

From: Wei Huang <wei.huang at intel.com>

Since 'rte_intr_callback_unregister()' can return positive
value as success, but 'ifpga_rawdev_destroy()' handle it as
an error.

Instead, only negative return is treated as failure.
