From 046b6a171009e1ed9ede02194025e9ccd709beb2 Mon Sep 17 00:00:00 2001 From: Guenter Roeck Date: Wed, 19 Apr 2023 09:41:27 -0700 Subject: device property: make device_property functions take const device * device_property functions do not modify the device pointer passed to them. The underlying of_device and fwnode_ functions actually already take const * arguments. Mark the parameter constant to simplify conversion from of_property to device_property functions, and to let the calling code use const device pointers where possible.
