Merge tag 'reset-fixes-for-4.11-2' of git://git.pengutronix.de/git/pza/linux into fixes
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"). * tag 'reset-fixes-for-4.11-2' of git://git.pengutronix.de/git/pza/linux: reset: add exported __reset_control_get, return NULL if optional Signed-off-by: Olof Johansson <olof@lixom.net>
