From fd96e35ea7b95f1e216277805be89d66e4ae962d Mon Sep 17 00:00:00 2001 From: Nathan Chancellor Date: Mon, 18 Oct 2021 11:25:37 -0700 Subject: [PATCH] platform/x86: thinkpad_acpi: Fix bitwise vs. logical warning A new warning in clang points out a use of bitwise OR with boolean expressions in this driver: drivers/platform/x86/thinkpad_acpi.c:9061:11: error: use of bitwise '|' with boolean operands [-Werror,-Wbitwise-instead-of-logical] else if ((strlencmp(cmd, "level disengaged") == 0) | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ || drivers/platform/x86/thinkpad_acpi.c:9061:11: note: cast one or both operands to int to silence this warning 1 error generated. This should clearly be a logical OR so change it to fix the warning.
