[PATCH] drm/msm: Don't use UTS_RELEASE directly

[PATCH] drm/msm: Don't use UTS_RELEASE directly

[Uwe Kleine-König (The Capable Hub)]

UTS_RELEASE evaluates to a static string and changes quite easily (e.g.
uncommitted changes in the source tree or new commits). So when checking
if a patch introduces changes to the resulting binary each usage of
UTS_RELEASE is source of annoyance.

Instead of using UTS_RELEASE directly use init_utsname()->release which
evaluates to the same string but with that a change of UTS_RELEASE
doesn't affect msm_disp_snapshot_util.o or msm_gpu.o.

Would you like to submit similar changes against driver/auxdisplay?

These didn't pollute my build results so far, so my pressure is small.
(Two of the three are not relevant for an allmodconfig build and the
third depends on PLAT_VERSATILE which isn't in my build matrix.)

I assume you ask because if I say no you'd address that? In that case
please go on.

Best regards
Uwe

Okay, noted.
Thanks for bringing in the way how to solve it!
