This is a well-structured 8-patch series fixing real bugs in the PowerVR (Imagination) GPU driver's job submission path, followed by cleanup/documentation improvements. The first two patches fix correctness issues where `prepare_job()` underestimates CCCB space requirements for paired geometry+fragment job submissions, leading to kernel warnings and potential job timeouts. The remaining 6 patches are sensible cleanup: removing dead code, extracting helpers, renaming for clarity, and improving comments.

The bug fixes are well-motivated with concrete kernel warning traces. The code changes are logically sound and the series is well-ordered (fixes first, then cleanups that depend on the fixes). Overall this looks good to merge.

**Verdict**: Series looks correct and well-motivated. Minor comments below, nothing blocking.
