What is the best practise to back port a linux driver ?

chakibdace

Hi all,

I'm currently using Linux kernel v5.10, i'm need to backport the isl7998x video decoder driver which was added in the v5.18 kernel, i'm wondering how can i backport this driver from v5.18 to v5.10 with avoid kernel compilation errors and if there is some useful setps to follow or i've to to change and adapt the code manually in the isl7998 driver code to support 5.10 v4l api features ?

Can you please tell me what are the best practices ?

Thanks

@arochester i'm first gonna try to compile this latter in Ubuntu 20.04 x86_64 with kernel 5.10, and then i'll try to cross compile the isl7998 driver for the NVIDIA Jetson AGX Orin platform (arch : arm64) which also run on Ubuntu 20.04 with kernel 5.10
