Extend copyright note to 2007, c.f. Kristian's git log.
Includes:
- replace some <asm/*.h> by <linux/*.h>
- add required indirectly included <linux/spinlock.h>
- order alphabetically
Coding style related changes:
- change to utf8
- normalize whitespace
- normalize comment style
- remove usages of __FUNCTION__
- remove an unnecessary cast from void *
Const and static declarations:
- driver_name is not const in pci_driver.name, drop const qualifier
- driver_name can be taken from KBUILD_MODNAME
- the global variable minors[] can and should be static
- constify struct file_operations instance
Data types:
- Remove unused struct member struct packet.code. struct packet is
only used for driver-internal bookkeeping; it does not appear on the
wire or in DMA programs or the userspace ABI. Hence the unused
member .code can be removed without worries.
Preprocessor macros:
- unroll a preprocessor macro that containd a return
- use list_for_each_entry
Printk:
- add missing terminating \n in some format strings
