Subject: [PATCH] serial: 8250_dw: Mark acpi match table as maybe unused
Date: Thu, 30 Sep 2021 21:49:50 +0900	[thread overview]
Message-ID: <20210930124950.3069638-1-daniel@0x0f.com> (raw)

When building kernels without ACPI support the table is declared
but is not used because ACPI_PTR() turns it into a NULL.

Add the __maybe_unused attribute to stop the compiler whining.
