Subject: [PATCH 5.10 065/125] thermal/drivers/rcar_gen3_thermal: Do not shadow rcar_gen3_ths_tj_1

From: Geert Uytterhoeven <geert+renesas@...der.be>

[ Upstream commit 3ae5950db617d1cc3eb4eb55750fa9d138529b49 ]

With -Wshadow:

    drivers/thermal/rcar_gen3_thermal.c: In function ‘rcar_gen3_thermal_probe’:
    drivers/thermal/rcar_gen3_thermal.c:310:13: warning: declaration of ‘rcar_gen3_ths_tj_1’ shadows a global declaration [-Wshadow]
      310 |  const int *rcar_gen3_ths_tj_1 = of_device_get_match_data(dev);
	  |             ^~~~~~~~~~~~~~~~~~
    drivers/thermal/rcar_gen3_thermal.c:246:18: note: shadowed declaration is here
      246 | static const int rcar_gen3_ths_tj_1 = 126;
	  |                  ^~~~~~~~~~~~~~~~~~

To add to the confusion, the local variable has a different type.

Fix the shadowing by renaming the local variable to ths_tj_1.
