> 1. fix arcmsr_device_id_table[] inits;
> 2. fix return (value); -- don't use parenethese
> 3. fix one-line-ifs-with-braces -- remove braces
> 4. struct _XYZ & typedef XYZ, PXYZ -- convert to struct XYZ only
> 5. check NULL usage
> 6. no "return;" at end of func; -- removed
> 7. return -ENXIO instead of ENXIO;
>
> Patch for above items is below.
>
> More issues, not yet patched:
>
> 8. check sparse warnings, stack usage, init/exit sections;
> 9. don't use // comments;
> 10. use printk levels
> 11. pPCI_DEV: bad naming (throughout driver; don't use mixed case)
> 12. some comments are unreadable (non-ASCII ?)
> 13. uintNN_t int types: use kernel types except for userspace interfaces
> 14. use kernel-doc

Erich, here are some more notes for you:
16. Tab size in Linux kernel is 8 (not less).
17. Don't put changelog comments in source files. That's what
SCMs are for (source code manager tools).
18. Put arcmsr.txt in Documentation/scsi/, not in scsi/arcmsr/.
19. Maybe use sysfs (/sys) instead of /proc.
---
From: Randy Dunlap <[email protected]>
More Areca (arcmsr) cleanups:
Fix about 1/2 of sparse warnings
(There are no stack size problems.)
Lots of long lines now fit into 80 columns (but not all of them).
Too much indentation in arcmsr_iop_ioctlcmd() and in arcmsr_info()
