[Qemu-devel] [PULL 10/14] checkpatch.pl: adjust typedef definition to QEMU coding style

[Paolo Bonzini <pbonzini@redhat.com>]

Most QEMU typedefs are camelcase, starting with one uppercase letter
and containing at least one lowercase letter.  There are a few
all-uppercase types, add the most common too.

This fixes recognition of types in lines such as

    static __attribute__((unused)) inline void tcg_out8(TCGContext *s, uint8_t v)

(Example provided by Peter Maydell).
