From ac5a2dff428ab59b5c5bbb4b28311141aa461c07 Mon Sep 17 00:00:00 2001 From: Nathan Chancellor Date: Fri, 13 Aug 2021 10:11:58 -0700 Subject: [PATCH] drm/i915/selftest: Fix use of err in igt_reset_{fail, nop}_engine() Clang warns: In file included from drivers/gpu/drm/i915/gt/intel_reset.c:1514: drivers/gpu/drm/i915/gt/selftest_hangcheck.c:465:62: warning: variable 'err' is uninitialized when used here [-Wuninitialized] pr_err("[%s] Create context failed: %d!\n", engine->name, err); ^~~ ... drivers/gpu/drm/i915/gt/selftest_hangcheck.c:580:62: warning: variable 'err' is uninitialized when used here [-Wuninitialized] pr_err("[%s] Create context failed: %d!\n", engine->name, err); ^~~ ... 2 warnings generated. This appears to be a copy and paste issue. Use ce directly using the %pe specifier to pretty print the error code so that err is not used uninitialized in these functions.
