------------------
From: Tom Stellard tstellar@redhat.com
[ Upstream commit 5612ea8b554375d45c14cbb0f8ea93ec5d172891 ]
This fixes the build with -Werror -Wall.
btf_dumper.c:71:31: error: variable 'finfo' is uninitialized when passed as a const pointer argument here [-Werror,-Wuninitialized-const-pointer] 71 | info.func_info = ptr_to_u64(&finfo); | ^~~~~
prog.c:2294:31: error: variable 'func_info' is uninitialized when passed as a const pointer argument here [-Werror,-Wuninitialized-const-pointer] 2294 | info.func_info = ptr_to_u64(&func_info); |
v2: - Initialize instead of using memset.
