[PATCH] Fixed IIO_DEVICE_ATTR_NAMED API to take name as a string and added "" around names

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

 



Fixed IIO_DEVICE_ATTR_NAMED API to take name as a
string instead of implicit conversion to string using
preprocessors. Added double quotes around names in
existing usage of IIO_DEVICE_ATTR_NAMED.
