    drivers/firmware: const-ify DMI API and internals · 1855256c
    Jeff Garzik authored
    Three main sets of changes:
    
    1) dmi_get_system_info() return value should have been marked const,
       since callers should not be changing that data.
    
    2) const-ify DMI internals, since DMI firmware tables should,
       whenever possible, be marked const to ensure we never ever write to
       that data area.
    
    3) const-ify DMI API, to enable marking tables const where possible
       in low-level drivers.
    
    And if we're really lucky, this might enable some additional
    optimizations on the part of the compiler.
    
    The bulk of the changes are #2 and #3, which are interrelated.  #1 could
    have been a separate patch, but it was so small compared to the others,
    it was easier to roll it into this changeset.
