Hi!
I get following errors in syslog everytime I start playing audio disc with
my cdrom drive. Xmcd continues playing normally but these messages are
still bit annoying. Kernel version is 2.1.94. It's also present in earlier
kernels.

Apr 10 14:54:46 sasu8 kernel: ATAPI device hdc:
Apr 10 14:54:46 sasu8 kernel: Error: Not ready -- (Sense key=0x02)
Apr 10 14:54:46 sasu8 kernel: Logical unit not ready - in progress (sic) of becoming ready -- (asc=0x04, ascq=0x01)
Apr 10 14:54:46 sasu8 kernel: The failed "Play Audio MSF" packet command was:
Apr 10 14:54:46 sasu8 kernel: ^I"47 00 00 00 02 00 40 0f 4a 00 00 00 "

Cdrom is Funai 16x (E295X) and gives following output at boot:
Apr 10 15:17:09 sasu8 kernel: hdc: ATAPI 16X CDROM drive, 240kB Cache

To me it seems that drive is just telling that it's spinning up and nothing
more serious is going on. So I made this little patch which supresses that
error message. So is my assumption correct (or even near that)?
