Subject: [PATCH AUTOSEL 4.18 72/88] soc: qcom: smem: Correct check for global
 partition

From: Bjorn Andersson <bjorn.andersson@...aro.org>

[ Upstream commit 0b65c59e3a5475895c93ea5f130597db16b8abf6 ]

The moved check for the global partition ended up in the wrong place and I
failed to spot this in my review. This moves it to the correct place.

Fixes: 11d2e7edac6a ("soc: qcom: smem: check sooner in qcom_smem_set_global_partition()")
