mcb: Fixed bar number assignment for the gdd

2016-06-01T19:15:53Z

commit f75564d343010b025301d9548f2304f48eb25f01 upstream. The bar number is found in reg2 within the gdd. Therefore we need to change the assigment from reg1 to reg2 which is the correct location.

mcb: Do not return zero on error path in mcb_pci_probe()

2015-10-29T00:02:16Z

There is an error path in mcb_pci_probe() where it returns zero instead of error code. Found by Linux Driver Verification project (linuxtesting.org). Signed-off-by: Alexey Khoroshilov Signed-off-by: Johannes Thumshirn Signed-off-by: Greg Kroah-Hartman

mcb: Fix error handling in mcb_pci_probe()

2015-10-05T04:10:01Z

If a MCB PCI Carrier device is IO mapped insted of memory-mapped, the memory of the PCI device is still not unmapped. Also the patch adds deallocation of the bus if chameleon_parse_cells() fails.

mcb: request_mem_region() returns NULL on error

2015-04-03T14:15:30Z

The code here is checking for IS_ERR() when request_mem_region() only returns NULL on error and never an ERR_PTR. Signed-off-by: Dan Carpenter Signed-off-by: Greg Kroah-Hartman

mcb: Fix error path of mcb_pci_probe

2015-02-03T23:48:51Z

If a MCB PCI Carrier device is IO mapped insted of memory-mapped (which is currently unsupported by the upstream driver) the probe function bails out with -ENOTSUPP. In this case the memory of the PCI device was not unmapped. Also rename error label to reflect what will happen at the destination (suggested by Julia Lawall .

mcb: mcb-pci: Only remap the 1st 0x200 bytes of BAR 0

2015-01-09T23:46:37Z

Currently it is not possible to have a kernel with built-in MCB attached devices. This results out of the fact that mcb-pci requests PCI BAR 0, then parses the chameleon table and calls the driver's probe function before releasing BAR 0 again. When building the kernel with modules this is not a problem (and therefore it wasn't detected by my tests yet). A solution is to only remap the 1st 0x200 bytes of a Chameleon PCI device. 0x200 bytes is the maximum size of a Chameleon v2 Table. Also this patch stops disabling the PCI device on successful registration of MCB devices.
