Build failure on driver sompilation

[paladin1974]

Hi,

I bought the TBS5930 and plan to run in on OpenSuse 15.3 X86_64. I followed the build instructions (git commit ff326ab69e786d447a0e0e967cb45acb5d5ca9ff (HEAD -> latest, origin/latest, origin/HEAD)) but the build failed cause sort_r is not in #include <linux/sort.h>
(uname: 5.3.18-150300.59.106-default #1 SMP Mon Dec 12 13:16:24 UTC 2022 (774239c) x86_64 x86_64 x86_64 GNU/Linux)


Here is the build log:

I checked the internet but could not find any reference to sort_r().
