kernel-4.19 irq xxx: nobody cared (try booting with the "irqpoll" option)
hi, 音视频通过 rk628d (HDMIRX)输入到 --> RK3568(MIPI CSI)，HDMI热插拔中断号101，对应gpio为 GPIO2,RK_PD0 （VCCIO5 <---1.8V) 插拔PC端HDMI线，概率出现如下错误:

For those who met this problem - in my case this happened due to wrong pins configuration and wrong voltage levels between AP and RK628. What really happened in my case: RK628 set HDMIRX_INT to 0. Due to some pullups from AP side - there is always logical '1' on the interrupt pin and irq handler called constantly. But no interrupt source is detected. After many many times irq called kernel disables IRQ and print "nobody cared".
But I see that in original issue this is printed for another IRQ - plugin DET. Well, levels, polarities and other can affect here too.
