Subject: [PATCH] serial: 8250_pci: Don't specify conflicting values to pci_device_id members
Date: Wed, 3 Jun 2026 11:56:16 +0200 [thread overview]
Message-ID: <20260603095616.937968-2-u.kleine-koenig@baylibre.com> (raw)
The PCI_VDEVICE macro assigns 0 to .class and .class_mask to allow the
next value in the initializer to define the value for .driver_data.
So the construct
{
PCI_VDEVICE(INTASHIELD, 0x0D21),
.class = PCI_CLASS_COMMUNICATION_MULTISERIAL << 8,
.class_mask = 0xffff00,
.driver_data = pbn_b2_4_115200,
},
introduced in commit 44e55f1f3088 ("serial: 8250_pci: Consistently
define pci_device_ids using named initializers") has conflicting
assignments. In only some configurations (i.e. W=1 for me) that makes
the compiler unhappy.
So convert the two affected items to PCI_DEVICE which doesn't have that
hidden assigment to .class and .class_mask.
Fixes: 44e55f1f3088 ("serial: 8250_pci: Consistently define pci_device_ids using named initializers")
