Subject: [dpdk-dev] [PATCH] drivers: ifpga_rawdev: fix fd leak in rte_fpga_do_pr
Date: Tue,  9 Apr 2019 07:32:21 -0700	[thread overview]
Message-ID: <20190409143221.16396-1-liq3ea@163.com> (raw)
Message-ID: <20190409143221.dDJsYHcnpWirujIVj6zEDKetYa0gfRs46S_UX7jCXPM@z> (raw)

In rte_fpga_do_pr() function, if 'stat' return error the
'file_fd' is never closed thus leading a fd leak. This patch
avoids this.
