As discussed in #1392 , a use after free bug in the kernel prevents heads kernel being compiled on debian 12.
This has been fixed in #1393 for boards using 5.10.5
The bug also affects boards using kernel 4.14.62. This PR will fix this and allow building of boards using this kernel on debian 12.
Clearly the future is for all boards to use 5.10 kernels (as per WIP #1381). Nevertheless, might be sensible to fix in 4.14 branch in the interim until no boards use the old kernel.
