Subject: [PATCH 1/3] ACPI: Remove acpi_has_method() call from acpi_adxl.c
Date: Sun, 21 Jul 2019 20:35:28 -0600	[thread overview]
Message-ID: <20190722023530.67676-2-skunberg.kelsey@gmail.com> (raw)
In-Reply-To: <20190722023530.67676-1-skunberg.kelsey@gmail.com>

acpi_check_dsm() will already return an error if the DSM method does not
exist. Checking if the DSM method exists before the acpi_check_dsm() call
is not needed. Remove acpi_has_method() call to avoid additional work.
