vme: Fix wrong pointer utilization in ca91cx42_slave_get
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@gmail.com> Acked-By: Martyn Welch <martyn@welchs.me.uk> Cc: stable <stable@vger.kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
