Perhaps this would be better just using dev_printk
instead of snprintf into a prefix with printk to
emulate dev_printk.
Also, perhaps KERN_NOTICE is preferable to KERN_WARNING
in the CORRECTABLE case.
Maybe something like:
const char *level = KERN_ERR;
if (aer_severity == AER_CORRECTABLE)
level = KERN_NOTICE;
...
dev_printk(level, &dev->dev, etc...);
Maybe do this after this series of patches is accepted.
Enough with the revisions for awhile...
