Thanks! I'll build a test kernel and ask the reporter for testing with it.

...llGraphSCCPass. Then, I implement my own runOnFunction method which tries to get alias analysis from each function. The code is shown as follows: *class AnalysisDriver : public CallGraphSCCPass {* * static char Pid;* * PassManager &passMgr;* * * *public:* * AnalysisDriver(PassManager &pmgr);* * ~AnalysisDriver();* * * * virtual void getAnalysisUsage(AnalysisUsage &AU) const {* * AU.addRequired<CallGraph>();* * AU.addRequired<AliasAnalysis>();* * AU.addPreserved<AliasAnalysis>();* * }* * * * bool run(Module &module);* * virtual bool runOnSCC(Ca...

We can't simply free the connector after calling drm_connector_init on it. We need to clean up the drm side first. It might not fix all regressions from 2b5d1c29f6c4 ("drm/nouveau/disp: PIOR DP uses GPIO for HPD, not PMGR AUX interrupts"), but at least it fixes a memory corruption in error handling related to that commit.
