Subject: [PATCH] ACPI: nfit: check dcr immediately following its assignment codes

From: Ocean He <hehy1@...ovo.com>

In commit 6697b2cf69d43632 ("nfit: fix multi-interface dimm handling,
acpi6.1 compatibility"), the check codes of dcr were just following its
assignment codes. But they were separated by commit ad9ac5e1957531a8
("nfit: always associate flush hints").

Just change the check codes back to original position, without function
change.
