Subject: [PATCH 5.8 494/633] soc: qcom: pdr: Fixup array type of get_domain_list_resp message

From: Sibi Sankar <sibis@...eaurora.org>

[ Upstream commit 7a366707bb6a93baeb1a9ef46c4b9c875e0132d6 ]

The array type of get_domain_list_resp is incorrectly marked as NO_ARRAY.
Due to which the following error was observed when using pdr helpers with
the downstream proprietary pd-mapper. Fix this up by marking it as
VAR_LEN_ARRAY instead.

Err logs:
qmi_decode_struct_elem: Fault in decoding: dl(2), db(27), tl(160), i(1), el(1)
failed to decode incoming message
PDR: tms/servreg get domain list txn wait failed: -14
PDR: service lookup for tms/servreg failed: -14
