Subject: [PATCH] cpufreq: scpi-cpufreq: signedness bug in scpi_get_dvfs_info()

From: Dan Carpenter <dan.carpenter@...cle.com>

The "domain" variable needs to be signed for the error handling to work.

Fixes: 8def31034d03 ('cpufreq: arm_big_little: add SCPI interface driver')

Hi Rafael,

This patch seem to have slipped through the cracks somehow. I don't see
in patchwork too. So I am resending so that you can pick for your next
rc fix if you plan to send one else for -next

Regards,
Sudeep
