Re: [PATCH -next] drm/bridge: lt8912b: DRM_LONTIUM_LT8912B select GPIOLIB

[zhangjianhua (E)]

Hello Robert

I am sorry that I make a mistake about the compiling error of lt8912b,

the reason is that lt8912b miss the header file <linux/gpio/consumer.h>.

Although there are many files reference gpiod_set_value_cansleep() and

devm_gpiod_get_optional(), they all include <linux/gpio/consumer.h>

and not occur the compiling error like lt8912b. I have send the second

version patch, please read.


Best regards,

Zhang Jianhua
