Subject: [PATCH v1 7/9] x86/platform/intel-mid: Drop unused __intel_mid_cpu_chip and Co.
Date: Thu, 11 Feb 2021 15:40:06 +0200	[thread overview]
Message-ID: <20210211134008.38282-8-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20210211134008.38282-1-andriy.shevchenko@linux.intel.com>

Since there is no more user of this global variable and associated custom API,
we may safely drop this legacy reinvented a wheel from the kernel sources.
