Agreed, patch below.

The change from __setup() to module_param_named() requires users to
prefix the option with "generic.".

This patch re-adds the __setup() additionally to the
module_param_named().

Usually it would make sense getting rid of such an obsolete __setup() at
some time, but considering that drivers/ide/ is slowly approaching a RIP
status it's already implicitely scheduled for removal.

This patch fixes kernel Bugzilla #7353.
