Subject: [PATCH] powerpc/perf/hv-24x7: Update domain value check
Date: Fri, 25 Aug 2023 11:26:01 +0530 [thread overview]
Message-ID: <20230825055601.360083-1-kjain@linux.ibm.com> (raw)
Valid domain value is in range 1 to HV_PERF_DOMAIN_MAX.
Current code has check for domain value greater than or
equal to HV_PERF_DOMAIN_MAX. But the check for domain value 0
is missing.
Fix this issue by adding check for domain value 0.
Fixes: ebd4a5a3ebd9 ("powerpc/perf/hv-24x7: Minor improvements")
Reported-by: Krishan Gopal Sarawast <krishang@linux.vnet.ibm.com>
