Subject: [PATCH] dw_mmc: The stupid ASUS Reboot patch
|
|
|
|
The patch didn't apply in the 4.16-rc4 so it had to be "rewritten".
|
|
By "rewritten", I mean, move the code blocks accordingly, based on
|
|
the new dw_mmc.c file layout.
|
|
|
|
No major changes were done.
|
|
|
|
It's still fucking ugly but I have no time to concentrate on this
|
|
issue and deal with it accordingly.
|
|
