2013-01-29Merge branch 'master' into for-nextJiri Kosina1-3/+3
Conflicts: drivers/devfreq/exynos4_bus.c Sync with Linus' tree to be able to apply patches that are against newer code (mvneta).
2013-01-21pcmcia: avoid static analysis complaint about use-after-freeJesper Juhl1-3/+3
Coverity complains about a use after free for 'res1' and 'res2' since we use the value of the pointers in a 'dev_dbg()' after they have been freed. That's not really a problem, but it still seems cleaner to defer freeing until we are completely done with the pointers.

Several fixes as well where the +1 was missing. Done via coccinelle scripts like: @@ struct resource *ptr; @@ - ptr->end - ptr->start + 1 + resource_size(ptr) and some grep and typing.

2010-09-29pcmcia: convert pcmcia_request_configuration to pcmcia_enable_deviceDominik Brodowski1-1/+0
pcmcia_enable_device() now replaces pcmcia_request_configuration(). Instead of config_req_t, all necessary flags are either passed as a parameter to pcmcia_enable_device(), or (in rare circumstances) set in struct pcmcia_device -> flags. With the last remaining user of include/pcmcia/cs.h gone, remove all references.

As we only provide one way to set up resources now, we can remove the resource-setup-related bitfield (except resource_setup_done).

2010-05-10pcmcia: do not autoadd root PCI bus resourcesDominik Brodowski1-6/+29
On the PCI root bus on the x86 architecture, the risk of hitting some strange system devices is too high: If a driver isn't loaded, the resources are not claimed; even if a driver is loaded, it may not request all resources or even the wrong one. We can neither trust the rest of the kernel nor ACPI/PNP and CRS parsing to get it right. Therefore, explicitly spell out what safeguards we provide, and add a safeguard to only use resources which are set up exclusively for the secondary PCI bus (non-subtractive mode): the risk of hitting system devices is quite low, as they usually aren't connected to the secondary PCI bus.

2010-05-10pcmcia: clarify alloc_io_space, move it to resource handlersDominik Brodowski1-11/+94
Clean up the alloc_io_space() function by moving most of it to the actual resource_ops. This allows for a bit less re-directions. Future cleanups will follow, and will make up for the code duplication currently present between rsrc_iodyn and rsrc_nonstatic (which are hardly ever built at the same time anyway, therefore no increase in built size).

- pcmcia_align() used a "start" variable twice.

On x86 systems using ACPI _CRS information -- now the default for post-2008 systems -- the PCI root bus no longer pretends to be offering the root ioport_resource.

2010-02-25pcmcia: validate late-added resourcesDominik Brodowski1-19/+48
Currently, only those mem resources are validated which are already registered at the time the first PCMCIA card is inserted. As we can only validate resources immediately after card insert, store "registered" mem resources in mem_db, and only upon validation move them to mem_db_valid. When allocationg mem resources, mem_db_valid is then preferred to mem_db. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
2010-02-23PCI: add pci_bus_for_each_resource(), remove direct bus->resource[] refsBjorn Helgaas1-2/+1
No functional change; this converts loops that iterate from 0 to PCI_BUS_NUM_RESOURCES through pci_bus resource[] table to use the pci_bus_for_each_resource() iterator instead. This doesn't change the way resources are stored; it merely removes dependencies on the fact that they're in a table.

2009-10-19pcmcia: pccard_read_tuple and TUPLE_RETURN_COMMON cleanupDominik Brodowski1-1/+1
pccard_read_tuple(), which is only used by the PCMCIA core, should handle TUPLE_RETURN_COMMON more sensibly: If a specific function (which may be 0) is requested, set tuple.Attributes = 0 as was done in all PCMCIA drivers. If, however, BIND_FN_ALL is requested, return the "common" tuple. As to the callers of pccard_read_tuple(): - All calls to pcmcia_validate_cis() had set the "function" parameter to BIND_FN_ALL. Therefore, remove the "function" parameter and make the parameter to pccard_read_tuple explicit. - Calls to CISTPL_VERS_1 and CISTPL_MANFID now set BIND_FN_ALL. This was already the case for calls to CISTPL_LONGLINK_MFC. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
