Subject: [PATCH v2 5/8] i2c: mlxbf: Refactor _UID handling to use acpi_dev_uid_to_integer()
Date: Thu, 8 Sep 2022 16:29:07 +0300 [thread overview]
Message-ID: <20220908132910.62122-6-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20220908132910.62122-1-andriy.shevchenko@linux.intel.com>
ACPI utils provide acpi_dev_uid_to_integer() helper to extract _UID as
an integer. Use it instead of custom approach.
Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com>
