[PATCH 6.12 101/206] thermal/drivers/sprd: Fix temperature clamping in sprd_thm_temp_to_rawdata

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

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

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

From: Thorsten Blum <thorsten.blum@linux.dev>

commit 83c0f9a5d679a6f8d84fc49b2f62ea434ccab4b6 upstream.

The temperature was never clamped to SPRD_THM_TEMP_LOW or
SPRD_THM_TEMP_HIGH because the return value of clamp() was not used. Fix
this by assigning the clamped value to 'temp'.

Casting SPRD_THM_TEMP_LOW and SPRD_THM_TEMP_HIGH to int is also
redundant and can be removed.
