'struct pci_device_id' is not modified in these drivers. Constifying this structure moves some data to a read-only section, so increases overall security. On a x86_64, with allmodconfig, as an example: Before: ====== text data bss dec hex filename 4073 1336 0 5409 1521 drivers/uio/uio_cif.o After: ===== text data bss dec hex filename 4233 1176 0 5409 1521 drivers/uio/uio_cif.o Signed-off-by: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx> --- Compile tested only. checkpatch generates some errors, but checkpatch is wrong. It does not have enough context to see that the arrays do have a sentinel. --- drivers/uio/uio_aec.c | 2 +- drivers/uio/uio_cif.c | 2 +- drivers/uio/uio_netx.c | 2 +- drivers/uio/uio_sercos3.c | 2 +- 4 files changed, 4 insertions(+), 4 deletions(-) diff --git a/drivers/uio/uio_aec.c b/drivers/uio/uio_aec.c index 8c164e51ff9e..dafcc5f44f24 100644 --- a/drivers/uio/uio_aec.c +++ b/drivers/uio/uio_aec.c @@ -33,7 +33,7 @@ #define MAILBOX 0x0F -static struct pci_device_id ids[] = { +static const struct pci_device_id ids[] = { { PCI_DEVICE(PCI_VENDOR_ID_AEC, PCI_DEVICE_ID_AEC_VITCLTC), }, { 0, } }; diff --git a/drivers/uio/uio_cif.c b/drivers/uio/uio_cif.c index 1cc3b8b5a345..4e4b589ddef1 100644 --- a/drivers/uio/uio_cif.c +++ b/drivers/uio/uio_cif.c @@ -105,7 +105,7 @@ static void hilscher_pci_remove(struct pci_dev *dev) iounmap(info->mem[0].internal_addr); } -static struct pci_device_id hilscher_pci_ids[] = { +static const struct pci_device_id hilscher_pci_ids[] = { { .vendor = PCI_VENDOR_ID_PLX, .device = PCI_DEVICE_ID_PLX_9030, diff --git a/drivers/uio/uio_netx.c b/drivers/uio/uio_netx.c index a1a58802c793..18917b2ac04c 100644 --- a/drivers/uio/uio_netx.c +++ b/drivers/uio/uio_netx.c @@ -127,7 +127,7 @@ static void netx_pci_remove(struct pci_dev *dev) iounmap(info->mem[0].internal_addr); } -static struct pci_device_id netx_pci_ids[] = { +static const struct pci_device_id netx_pci_ids[] = { { .vendor = PCI_VENDOR_ID_HILSCHER, .device = PCI_DEVICE_ID_HILSCHER_NETX, diff --git a/drivers/uio/uio_sercos3.c b/drivers/uio/uio_sercos3.c index b93a5f8f4cba..12afc2fa1a0b 100644 --- a/drivers/uio/uio_sercos3.c +++ b/drivers/uio/uio_sercos3.c @@ -191,7 +191,7 @@ static void sercos3_pci_remove(struct pci_dev *dev) } } -static struct pci_device_id sercos3_pci_ids[] = { +static const struct pci_device_id sercos3_pci_ids[] = { { .vendor = PCI_VENDOR_ID_PLX, .device = PCI_DEVICE_ID_PLX_9030, -- 2.50.1
