 | |
| 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.
 | |
