Hi,

Change return type of cedrus_find_format to bool as it is only called
once, by a function whose return value is bool, and the return value of
cedrus_find_format is returned as-is at the call-site.
Issue found with Coccinelle.
The purpose of this function (although definitely under-used at this point),
was to return the pointer to the element structure, not to indicate whether
the format format is part of the list or not.
In spite of that, this change reduces the use case for the function, so I do
not think it is beneficial, sorry.
Okay, thank you for the clarification.

Cheers,
