[PATCH v2] OMAP: hwmod: Do not expect an entry in clkdev for opt_clks

On Wed, 2 Feb 2011, Rajendra Nayak wrote:

The _add_optional_clock_alias function expects an entry
already existing in the clkdev table in the form of
<dev-id=NULL, con-id=role> which might not be the case
always.

Instead, just check if an entry already exists in clkdev
in the <dev-id=dev_name, con-id=role> form, else go ahead
and add one.

Remove any assumption of an entry already existing in clkdev
table in any form.

Since this means, adding a new entry in clkdev if it does
not already exist, and not really adding an 'alias',
also rename the function name
(s/_add_optional_clock_alias/_add_optional_clock_clkdev)
to reflect this.

Thanks.  I changed the subject line to read:
