[PATCH] kmsg_write: don't return printk return value
kmsg_write returns with printk, so some programs may be confused by a
successful write() with a return value different than the buffer length.
# /bin/echo something > /dev/kmsg
/bin/echo: write error: Inappropriate ioctl for device
The drawbacks is that the printk return value can no more be quickly
checked from userspace.
