[ Upstream commit fd96e35ea7b95f1e216277805be89d66e4ae962d ]
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.
