Works around get_user_pages argument error when compiling for kernel 6.5 or newer
|
||
|
|
Should work with 525xx, 530xx 535xx prior to 535.86(?), potentially some older versions?
|
||
|
|
Original patch by Fjodor42 - this just changes some driver-specific lines
|
||
|
|

Original original patch for 470xx by Joan Bruguera at https://gist.github.com/joanbm/dfe8dc59af1c83e2530a1376b77be8ba
