Subject: [PATCH] thermal: intel: Fix unsigned comparison with less than zero
Git-commit: e7fcfe67f9f410736b758969477b17ea285e8e6c
Patch-mainline: v6.3-rc1
References: git-fixes
The return value from the call to intel_tcc_get_tjmax() is int, which can
be a negative error code. However, the return value is being assigned to
an u32 variable 'tj_max', so making 'tj_max' an int.
Eliminate the following warning:
./drivers/thermal/intel/intel_soc_dts_iosf.c:394:5-11: WARNING: Unsigned expression compared with zero: tj_max < 0
