From 77005bc23dfca72e2466486e3b9c25a7e9136a22 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Thu, 24 Oct 2024 22:04:52 +0300 Subject: [PATCH] iio: imu: inv_mpu6050: Replace strange way of checking type of enumeration When device is enumerated via ACPI the respective device node is of ACPI device type. Use that to check for ACPI enumeration, rather than calling for full match which is O(n) vs. O(1) for the regular check.
