Subject: [dpdk-dev] [PATCH v2] raw/ifpga: fix ifpga device name format
Date: Wed, 28 Apr 2021 22:26:40 -0400	[thread overview]
Message-ID: <20210429022640.39444-1-wei.huang@intel.com> (raw)

The device name format used in ifpga_rawdev_create() was changed to
"IFPGA:%02x:%02x.%x", but the format used in ifpga_rawdev_destroy()
was left as "IFPGA:%x:%02x.%x", it should be changed synchronously.
To prevent further similar errors, macro "IFPGA_RAWDEV_NAME_FMT" is
defined to replace this format string.

Fixes: 9c006c45d0c5 ("raw/ifpga: scan PCIe BDF device tree")
