From 047c25401d2b4001e7e20200a5ec05868a113290 Mon Sep 17 00:00:00 2001 From: Wei Huang Date: Wed, 16 Mar 2022 03:26:30 -0400 Subject: [PATCH] raw/ifpga: fix build with optimization 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.
