[PATCH 5.4 037/177] iio: adis16480: Add debugfs_reg_access entry

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Nuno Sá <nuno.sa@xxxxxxxxxx>

commit 4c35b7a51e2f291471f7221d112c6a45c63e83bc upstream.

The driver is defining debugfs entries by calling
`adis16480_debugfs_init()`. However, those entries are attached to the
iio_dev debugfs entry which won't exist if no debugfs_reg_access
callback is provided.

Fixes: 2f3abe6cbb6c ("iio:imu: Add support for the ADIS16480 and similar IMUs")
