[yocto] [psplash][PATCH 2/5] psplash-fb: fix sign-compare warning

[Richard Leitner]

Cast font->index[i] to wchar_t for the comparison.

This fixes following sign-compare warning:

psplash-fb.c: In function 'psplash_font_glyph':
psplash-fb.c:452:33: warning: comparison between signed and unsigned
integer expressions [-Wsign-compare]
