Subject[PATCH AUTOSEL 6.1 02/10] platform/x86/amd/pmf: Fix unsigned comparison with less than zero
Date
From: Yang Li <yang.lee@linux.alibaba.com>

[ Upstream commit 785c00993dc4c4bb2f7b0f3a3f29c03a6f7aab2e ]

The return value from the call to amd_pmf_get_pprof_modes() is int.
However, the return value is being assigned to an unsigned char
variable 'mode', so making 'mode' an int.

silence the warning:
./drivers/platform/x86/amd/pmf/sps.c:183:5-9: WARNING: Unsigned expression compared with zero: mode < 0
