4.19-stable review patch. If anyone has any objections, please let me know. ------------------ From: Daniel Lezcano <daniel.lezcano@xxxxxxxxxx> [ Upstream commit e2c77032fcbe515194107994d12cd72ddb77b022 ] The macros for the unit conversion for frequency are duplicated in different places. Provide these macros in the 'units' header, so they can be reused.
