Some checks failed
Continues testing / build (push) Has been cancelled
The ION staging drivers still reference legacy relative UAPI paths (../uapi/ion.h and ../uapi/msm_ion.h) which no longer exist in modern Android kernels. Update all ION sources to include the canonical UAPI headers from include/uapi/linux instead. This aligns the tree with upstream Android kernel behavior and fixes build failures when using modern toolchains.
