Michael Jones 4359d38d51 omap: iovmm: disallow mapping NULL address when IOVMF_DA_ANON is set
commit c7f4ab26e3bcdaeb3e19ec658e3ad9092f1a6ceb allowed mapping the NULL
address if da_start==0, which would then not get unmapped. Disallow
this again if IOVMF_DA_ANON is set. And spell variable 'alignment'
correctly.
