These functions have been deprecated for some time now but remained until
all legacy callers could be removed.  With a few commits in 2.6.26 this
has happened so now we can remove these deprecated functions.

The current implementation reports the structure name as

That doesn't make sense because it's always the same. Instead, use the

That's also what the 'makedumpfile -g' does.

According to MMC-3 (or any later versions) READ TOCs are mandatory

the check was put there in the first place but it now only breaks
automatic actions on certain drives.

Note that this test was only effective when ide-cdrom was being used
as sr didn't mask CDC_PLAY_AUDIO according to the capabilities.

The guilty commit turned out to be 08da591e
("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).
