From 1c3b2f4ae1da02f173315b1fc02b05122c02bd44 Mon Sep 17 00:00:00 2001 From: Tom Rini Date: Sun, 30 Sep 2018 10:38:15 -0400 Subject: [PATCH] efi_loader: Fix warning in efi_load_image() As observed with clang: lib/efi_loader/efi_boottime.c:1624:7: warning: variable 'info' is used uninitialized whenever 'if' condition is true [-Wsometimes-uninitialized] if (ret != EFI_SUCCESS) ^~~~~~~~~~~~~~~~~~ lib/efi_loader/efi_boottime.c:1653:7: note: uninitialized use occurs here free(info); ^~~~ lib/efi_loader/efi_boottime.c:1624:3: note: remove the 'if' if its condition is always false if (ret != EFI_SUCCESS) ^~~~~~~~~~~~~~~~~~~~~~~ lib/efi_loader/efi_boottime.c:1602:31: note: initialize the variable 'info' to silence this warning struct efi_loaded_image *info; ^ = NULL Rather than change how we unwind the function it makes the most sense to initialize info to NULL so that we can continue to pass it to free().
