Subject: [PATCH 6/9] platform/x86:intel/pmc: Remove unneeded min_t check
Date: Mon, 24 Jun 2024 13:32:15 -0700	[thread overview]
Message-ID: <20240624203218.2428475-7-xi.pardee@linux.intel.com> (raw)
In-Reply-To: <20240624203218.2428475-1-xi.pardee@linux.intel.com>

min_t() check is not needed in pmc_core_ltr_ignore_write().
kstrtox() has a built-in overflow check.
