[PATCH] iio: Fix iio_channel_has_info

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

 



Since the info_mask split, iio_channel_has_info() is not working correctly.
info_mask_separate and info_mask_shared_by_type, it is not possible to compare
them directly with the iio_chan_info_enum enum. Correct that bit using the BIT()
macro.
