This is an experimental semi-automated report about issues detected by Coverity from a scan of next-20221110 as part of the linux-next scan project: https://scan.coverity.com/projects/linux-next-weekly-scan You're getting this email because you were associated with the identified lines of code (noted below) that were touched by commits: Mon Aug 31 19:10:08 2020 -0400 a0922278f83e ("drm/nouveau/kms/nv50-: Refactor and cleanup DP HPD handling") Coverity reported the following: *** CID 1527266: Null pointer dereferences (REVERSE_INULL) drivers/gpu/drm/nouveau/nouveau_dp.c:237 in nouveau_dp_irq() 231 struct nouveau_encoder *outp = find_encoder(connector, DCB_OUTPUT_DP); 232 struct nouveau_drm *drm = nouveau_drm(outp->base.base.dev); 233 struct nv50_mstm *mstm; 234 u64 hpd = 0; 235 int ret; 236 vvv CID 1527266: Null pointer dereferences (REVERSE_INULL) vvv Null-checking "outp" suggests that it may be null, but it has already been dereferenced on all paths leading to the check. 237 if (!outp) 238 return; 239 240 mstm = outp->dp.mstm; 241 NV_DEBUG(drm, "service %s\n", connector->name); 242 If this is a false positive, please let us know so we can mark it as such, or teach the Coverity rules to be smarter. If not, please make sure fixes get into linux-next. :) For patches fixing this, please include these lines (but double-check the "Fixes" first): Reported-by: coverity-bot <keescook+coverity-bot@xxxxxxxxxxxx> Addresses-Coverity-ID: 1527266 ("Null pointer dereferences") Fixes: a0922278f83e ("drm/nouveau/kms/nv50-: Refactor and cleanup DP HPD handling") Thanks for your attention! -- Coverity-bot
