3.16.42-rc1 review patch. If anyone has any objections, please let me know. ------------------ From: Augusto Mecking Caringi <augustocaringi@xxxxxxxxx> commit c8a6a09c1c617402cc9254b2bc8da359a0347d75 upstream. In ca91cx42_slave_get function, the value pointed by vme_base pointer is set through: *vme_base = ioread32(bridge->base + CA91CX42_VSI_BS[i]); So it must be dereferenced to be used in calculation of pci_base: *pci_base = (dma_addr_t)*vme_base + pci_offset; This bug was caught thanks to the following gcc warning: drivers/vme/bridges/vme_ca91cx42.c: In function ‘ca91cx42_slave_get’: drivers/vme/bridges/vme_ca91cx42.c:467:14: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast] *pci_base = (dma_addr_t)vme_base + pci_offset; Signed-off-by: Augusto Mecking Caringi <augustocaringi@xxxxxxxxx> Acked-By: Martyn Welch <martyn@xxxxxxxxxxxx> Signed-off-by: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx> Signed-off-by: Ben Hutchings <ben@xxxxxxxxxxxxxxx> --- drivers/vme/bridges/vme_ca91cx42.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) --- a/drivers/vme/bridges/vme_ca91cx42.c +++ b/drivers/vme/bridges/vme_ca91cx42.c @@ -468,7 +468,7 @@ static int ca91cx42_slave_get(struct vme vme_bound = ioread32(bridge->base + CA91CX42_VSI_BD[i]); pci_offset = ioread32(bridge->base + CA91CX42_VSI_TO[i]); - *pci_base = (dma_addr_t)vme_base + pci_offset; + *pci_base = (dma_addr_t)*vme_base + pci_offset; *size = (unsigned long long)((vme_bound - *vme_base) + granularity); *enabled = 0;
