[PATCH 4.20 276/352] thermal: tsens: qcom: do not create duplicate regmap debugfs entries

[Greg Kroah-Hartman]

4.20-stable review patch.  If anyone has any objections, please let me know.

------------------

[ Upstream commit 4ab248b3b10a58e379e2d32333fff99ea5ca256c ]

Regmap would use device name to create debugfs entries. If the device
has multiple regmaps it is recommended to use name field in regmap_config.
Fix this by providing name to the regmap configs correctly.

Without this patch we would see below error on DB820c.

qcom-tsens 4a9000.thermal-sensor: Failed to create 4a9000.thermal-sensor
debugfs directory
