[PATCH v2 6/6] iio: iio_buffer_register: Use correct channel when calculating masklength

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

 



The channel set assigned to the iio device is not necessarily the same has the
channel set passed to iio_buffer_register. So to avoid possible complications
always work with the channel set pass to iio_buffer_register and ignore the
channel set assigned to the iio device.
