This happens in case the controller uses the default GPIO setter. Always use chip->set to access the setter to avoid possible NULL pointer dereferencing.

gpio: syscon: rockchip: add GRF GPIO support for rk3328 2018-08-06T21:46:55+00:00 Levin Du djw@t-chip.com.cn 2018-07-31T05:59:19+00:00 cf2ff877a4eea5f5ad959050284eb93d5d2f803a In Rockchip RK3328, the output only GPIO_MUTE pin, originally for codec mute control, can also be used for general purpose. It is manipulated by the GRF_SOC_CON10 register in GRF. Aside from the GPIO_MUTE pin, the HDMI pins can also be set in the same way. Currently this GRF GPIO controller only supports the mute pin. If needed in the future, the HDMI pins support can also be added.
