Hi all,
the patch is fine with me but i have a few basic questions:
Why the (void *) at all ? it returns a name what is a const char *.
We're really returning a pointer to a private struct, it's just that
the first element on the struct always has to be a pointer to char *.
To be pedantic, it's really returning a pointer to some member of type
'const char *' within a private struct. To make life easier for
themselves, those drivers make that the first member of the private
struct so a void pointer to the member is also a void pointer to the struct.
