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):
