24307ffabd cs5520: add enablebits checking
Based on sparse comments in OpenFirmware code
(no Cx5510/Cx5520 datasheet here).

This fixes 2.6.26 regression reported by TAKADA
and caused by addition of warm-plug support.

938bb03d18 ide-cd: fix endianity for the error message in cdrom_read_capacity
Aesthetic regards aside, commit e8e7b9eb11
still leaves a bug in the error message, because it uses the unconverted
big-endian value for printk.

Fix this by using a local variable in machine byte order. The result is
correct, more readable, and also produces slightly shorter code on i386.

c5bfc3757f ide: remove CONFIG_IDE_MAX_HWIFS
The benefits of a user settable CONFIG_IDE_MAX_HWIFS have become pretty 
tiny and are no longer considered worth the trouble of an own option.

Simply always #define MAX_HWIFS to 10.

The guilty commit turned out to be 08da591e14
("ide: add ide_device_{get,put}() helpers").  ide_device_put() is called
before kref_put() in ide_cd_put() so IDE device is already gone by the time
ide_cd_release() is reached.

Fix it by calling ide_device_get() before kref_get() and ide_device_put()
after kref_put() in all affected device drivers.

v2:
Brown paper bag time.  In v1 cd->drive was referenced after dropping last
reference on cd object (which could result in OOPS in ide_device_put() as
reported/debugged by Mariusz Kozlowski).  Fix it by caching cd->drive in
the local variable (fix other device drivers too).

IDE probing code used to skip devices attached to EATA SCSI HBA
in ATA emulating mode but because of warm-plug support port I/O
resources are no longer freed if no devices are detected on a port
and the decision about the driver to use is left up to the user.

Remove no longer valid EATA SCSI HBA quirk from do_identify().

e8e7b9eb11 ide-cd: fix oops when using growisofs
cdrom_read_capacity() will blindly return the capacity from the device
without sanity-checking it.  This later causes code in fs/buffer.c to
oops.

Fix this by checking that the device is telling us sensible things.
