Hello!

I am getting this from mainline and -next:

drivers/gpu/drm/msm/msm.o: warning: objtool: submit_lock_objects+0x391: sibling call from callable instruction with modified stack frame

I don't see anything suspicious in that function, but then again,
I wouldn't know what to be suspicious of.  I see this on x86_64
with:

gcc version 11.4.0 (Ubuntu 11.4.0-1ubuntu1~22.04)

and:

gcc version 11.5.0 20240719 (Red Hat 11.5.0-9) (GCC)

I have uploaded the msm.o file [1], in case that helps.

Please let me know if there is additional information that I can provide.

							Thanx, Paul
