Josh Poimboeuf c05a87d9ec iio: imu: bmi160: Remove potential undefined behavior in bmi160_config_pin() ... If 'pin' is not one of its expected values, the value of 'int_out_ctrl_shift' is undefined. With UBSAN enabled, this causes Clang to generate undefined behavior, resulting in the following warning: drivers/iio/imu/bmi160/bmi160_core.o: warning: objtool: bmi160_setup_irq() falls through to next function __cfi_bmi160_core_runtime_resume() Prevent the UB and improve error handling by returning an error if 'pin' has an unexpected value. While at it, simplify the code a bit by moving the 'pin_name' assignment to the first switch statement.
