Re: [PATCH] Fix regression caused by typo in lm90.c

Hi,

my original patch for this didn't have that typo, however I had spelled
it in small letters instead of capital letters. So I guess, the typo
sneaked in while switching from small to capital letter.

Main message: I can confirm that it actually is a typo :)

have a great day
/Rainer
