[PATCH 33/36] staging: comedi: ni_660x: rename the CamelCase enum NI_660x_Register and labels

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

 



As prefered by the CodingStyle, rename this CamelCase enum and its labels.

Also, cleanup the ni_gpct_to_660x_register() helper function. Just return the
ni_660x_register for each ni_gpct_register and remove the unnecessary break
statements after the return statements.
