Subject: [PATCH 5.16 014/227] serial: parisc: GSC: fix build when IOSAPIC is not set
Date: Mon, 21 Feb 2022 09:47:13 +0100 [thread overview]
Message-ID: <20220221084935.310770945@linuxfoundation.org> (raw)
In-Reply-To: <20220221084934.836145070@linuxfoundation.org>
From: Randy Dunlap <rdunlap@infradead.org>
commit 6e8793674bb0d1135ca0e5c9f7e16fecbf815926 upstream.
There is a build error when using a kernel .config file from
'kernel test robot' for a different build problem:
hppa64-linux-ld: drivers/tty/serial/8250/8250_gsc.o: in function `.LC3':
(.data.rel.ro+0x18): undefined reference to `iosapic_serial_irq'
when:
CONFIG_GSC=y
CONFIG_SERIO_GSCPS2=y
CONFIG_SERIAL_8250_GSC=y
CONFIG_PCI is not set
and hence PCI_LBA is not set.
IOSAPIC depends on PCI_LBA, so IOSAPIC is not set/enabled.
Make the use of iosapic_serial_irq() conditional to fix the build error.
