Subject: [PATCH v1] raw/ifpga: initialize variable to avoid compile error
Date: Wed, 16 Mar 2022 03:26:30 -0400 [thread overview]
Message-ID: <20220316072630.1916479-1-wei.huang@intel.com> (raw)
Compile failed with cflag optimization=1 on Ubuntu20.04 with GCC10.3,
it reported vendor_id and dev_id may be used uninitialized in function
ifpga_rawdev_fill_info().
Actually it's not the truth, the variables are initialized in function
ifpga_get_dev_vendor_id(). To avoid such compile error, the variables
are initialized when they are defined.
