HID: i2c-hid-of: fix NULL-deref on failed power up
A while back the I2C HID implementation was split in an ACPI and OF part, but the new OF driver never initialises the client pointer which is dereferenced on power-up failures. Fixes: b33752c30023 ("HID: i2c-hid: Reorganize so ACPI and OF are separate modules") Cc: stable@vger.kernel.org # 5.12 Cc: Douglas Anderson <dianders@chromium.org> Signed-off-by: Johan Hovold <johan+linaro@kernel.org> Reviewed-by: Douglas Anderson <dianders@chromium.org> Signed-off-by: Jiri Kosina <jkosina@suse.com>
