Combining the struct definition with its variable initializer confuses the
kernel-doc parser because __MUTEX_INITIALIZER() expands to contain braces,
breaking brace counting and causing:

  Warning: drivers/dma/dmatest.c:152 struct member '' not described in 'dmatest_info'

Split into separate struct definition and variable declaration, which is
the standard kernel pattern.
