From 2b498df75d6c29aa3e760127ae0f0003df598b53 Mon Sep 17 00:00:00 2001 From: Arka Mondal Date: Sun, 16 Aug 2026 03:27:26 +0900 Subject: [PATCH] iio: gyro: adis16136: fix unprotected debugfs reads The serial_number file operations are open coded and never call debugfs_file_get(), which debugfs_create_file_unsafe() requires. debugfs_remove_recursive() therefore does not wait for a read in progress, and unbind frees the iio_dev underneath it. Use debugfs_create_file() instead.
