Subject: [PATCH v1 2/2] usb: typec: intel_pmc_mux: Deduplicate ACPI matching in probe
Date: Mon,  2 Jan 2023 22:29:33 +0200	[thread overview]
Message-ID: <20230102202933.15968-2-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20230102202933.15968-1-andriy.shevchenko@linux.intel.com>

There is no need to call acpi_dev_present() followed by
acpi_dev_get_first_match_dev() as they both do the same
with only difference in the returning value. Instead,
call the latter and check its result.
