Subject: drm/msm/adreno: Do not propagate void return values
Git-commit: d7499634db4f43d3347ae58c5931ad1c795d4cbf
Patch-mainline: v6.0-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225 jsc#PED-2849

With sparse ("make C=2"), lots of

  error: return expression in void function

messages are seen.

Fix this by removing the return statements to propagate void return
values.
