From cec920f67e562821812b10f78334d91d81a4e26f Mon Sep 17 00:00:00 2001 From: Nuno Sa Date: Fri, 9 Aug 2024 11:17:06 +0200 Subject: iio: imu: adis16475: drop ifdef around CONFIG_DEBUG_FS Use IS_ENABLED(CONFIG_DEBUG_FS) to return early in case debugfs is not present. Since this is known at compile time, it allows the compiler to drop any unused code. Therefore no need to wrap the code with #ifdef.
