On Linux >= 2.6.33, use <generated/autoconf.h> instead of
<linux/autoconf.h>. Include it after <linux/version.h>.
Use generated/utsrelease.h as VERSION_HEADER if present instead of
linux/utsrelease.h or linux/version.h.
* 3dfx_driver.c (findCards): Return int instead of void , and normalize
error code to be always negative, otherwise return numCards.
(init_module): Check for findCards return code, print a warning and
exit the module on error.
(init_3dfx): Likewise.
LINUX_VERSION_CODE >= 2.3.46 and LINUX_VERSION_CODE <= 2.6.17 or
if DEVFS_SUPPORT is defined, define to 0 otherwise.
(devfs_handle): Only use if HAVE_DEVFS.
(init_module): Only use devfs_mk_cdev or devfs_register if HAVE_DEVFS.
(cleanup_module): Only use devfs_remove or devfs_unregister if
HAVE_DEVFS.
* kver.c: New file.
* Makefile: Include kver.mak.
(KVERS): Move this variable to 'kver.mak', which is a generated file.
(VERSION_HEADER): New variable to cope with UTS_RELEASE being moved
from 'linux/version.h' to 'linux/utsrelease.h' in 2.6.18.
(kver, kver.mak): New targets.
(KBUILD): New variable.
(KVER_MAJOR, KVER_MINOR, BUILD_TYPE, MODULE_TDFX): Likewise, moved
from the generated file 'config'.
(config, kinfo, kinfo.h): Remove targets.
(modules, intstall, clean): Do not depend on config target.
(modules, intstall): Depend on sanity target .
* 3dfx_device.c (pcibios_read_config_byte): Rename to ...
(pci_read_config_byte): ... this and remove first argument.
(pcibios_read_config_word): Rename to ...
(pci_read_config_word): ... this and remove first argument.
(pcibios_read_config_dword): Rename to ...
(pci_read_config_dword): ... this and remove first argument.
(pcibios_write_config_dword): Rename to ...
(pci_write_config_dword): ... this and remove first argument.
