As title, I porting the bcm4339 wifi module on Android 5 GA, it works, but when I turn off the wifi and turn on again,
it cannot works, kernel message as below:
======== Card detection to remove SDIO card! ========
dummy_sdmmc: probe of mmc1:0001:1 failed with error -110
dummy_sdmmc: probe of mmc1:0001:2 failed with error -110
I think it's due to the nonremovable sdio node definition for dts file, the only way is force mmc rescan when I turn off the wifi,
but how should I do? and how to fix this issue? it's serious.
I will share this patch if anyone solve this problem.
