[PATCH] hpfs: bring hpfs_error() into shape
- switch to error message buffer in .bss
- missing va_end() (htf it worked before?)
- use vsnprintf()
- rename variables to understandable "fmt", "args".
- "const char *fmt", yes.
- add __attribute__((format ...
Still, put that coffee down before reading more.
