Subject: [PATCH v2 2/8] platform/x86: intel_skl_int3472: Free ACPI device resources after use
Date: Fri, 18 Jun 2021 15:55:10 +0300	[thread overview]
Message-ID: <20210618125516.53510-2-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20210618125516.53510-1-andriy.shevchenko@linux.intel.com>

We may free ACPI device resources immediately after use.
Refactor skl_int3472_parse_crs() accordingly.
