Subject: [PATCH 01/10] dt-bindings: net: bluetooth: qualcomm: Fix WCN6855
 regulator names

From: Konrad Dybcio <konrad.dybcio@....qualcomm.com>

Commit 5f4f954bba12 ("dt-bindings: bluetooth: bring the HW description
closer to reality for wcn6855") changed the vddrfa1p7-supply to 1p8
for whatever reason.

The schematics footprint for this chip definitely says 7 on the input
leg and the driver still expects 1p7. Bring it back.

Fixes: 5f4f954bba12 ("dt-bindings: bluetooth: bring the HW description closer to reality for wcn6855")
