Subject: [PATCH] ASoC: qcom: q6prm: fix incorrect clk_root passed to ADSP
References: bsc#1012628
Patch-mainline: 6.2.8
Git-commit: 65882134bc622a1e57bd5928ac588855ea2e3ddd

commit 65882134bc622a1e57bd5928ac588855ea2e3ddd upstream.

The second to last argument is clk_root (root of the clock), however the
code called q6prm_request_lpass_clock() with clk_attr instead
(copy-paste error).  This effectively was passing value of 1 as root
clock which worked on some of the SoCs (e.g. SM8450) but fails on
others, depending on the ADSP.  For example on SM8550 this "1" as root
clock is not accepted and results in errors coming from ADSP.
