Subject: [PATCH RESEND v2 03/25] nls: Wrap charset hooks in ops structure
This is done in preparation to splitting the nls_table structure, in
order to support multiple versions of the same encoding. By placing all
the operations together, we can allow multiple operations for the same
encoding, depending on the version. For now, there is no behavior
change intended, but this simplify the following patches.
With the exception of the declaration of the structure, this patch was
generated by the following Coccinelle script:
<smpl>
@nlstable@
