Subject:    [Linux-fbdev-devel] [PATCH, 2.4] Fix inverse logo for FB_VISUAL_MONO01

Hello Geert,

this fixes the logo inversion logic for FB_VISUAL_MONO01. It also fixes
the declaration of a variable in the middle of a function, which isn't
allowed in traditional C.

2.4 only, as the 2.5 logo code has changed.
