Hello, guys.

 This patch implements ->tf_read callback for sil24.  It didn't use to
be necessary but new ata_gen_fixed_sense now makes use of ->tf_read
callback.  This patch is taken from Edward Falk's driver.

sil24 0.20 didn't use to perform (what seems to be) port multiplier
initialization and controller reset 0.10 driver does.  This makes some
sil24 controllers malfunction.  This patch adds PM initialization and
controller resetting to initilization and bumps version to 0.21.

02_sil24_remove-irq-disable-on-spurious-intr.patch

	If interrupt occurs on a disabled port, the driver used to
        mask the port's interrupt, but we don't know if such action is
        necessary yet and that's not what other drives do.  So, just
        do nothing and tell IRQ subsystem that it's not our interrupt.
