[PATCH v1 1/1] device property: Add const qualifier to device_get_match_data() parameter

From: Andy Shevchenko
Date: Thu Sep 22 2022 - 09:54:03 EST


Add const qualifier to the device_get_match_data() parameter.
Some of the future users may utilize this function without
forcing the type.

All the same, dev_fwnode() may be used with a const qualifier.
