Dear arm-soc maintainers,
please consider merging this tag for v4.11, which fixes another bug that
slipped through in commit bb475230b8e5 ("reset: make optional functions
really optional"). If RESET_CONTROLLER is enabled,
devm_reset_controller_get_optional must return NULL after the API
change, if called from a driver that is not probed via device tree
(dev->of_node == NULL). This is the case for recent Intel boards using
the 8250_dw driver, which will be changed to rely on that behaviour
in v4.12.
regards
Philipp

Reset controller fixes for v4.11
Fix devm_reset_controller_get_optional to return NULL for non-DT devices,
if the RESET_CONTROLLER Kconfig option is enabled. This fixes probe failures
of the 8250_dw driver on Intel platforms after commit acbdad8dd1ab ("serial:
8250_dw: simplify optional reset handling").
