Subject: [PATCH v3 5/5] perf: arm_spe: Enable ACPI/Platform automatic module loading
Date: Fri,  3 May 2019 18:24:07 -0500	[thread overview]
Message-ID: <20190503232407.37195-6-jeremy.linton@arm.com> (raw)
Message-ID: <20190503232407.sl7GcPOff4G6akp2kY6dWnr4R4ZCdKCRLGmyFX8rYOs@z> (raw)
In-Reply-To: <20190503232407.37195-1-jeremy.linton@arm.com>

Lets add the MODULE_TABLE and platform id_table entries so that
the SPE driver can attach to the ACPI platform device created by
the core pmu code.
