Subject[038/115] [media] radio-aimslab.c: Fix gcc 4.5+ bug
2.6.32-longterm review patch.  If anyone has any objections, please let us know.

------------------
From: Mauro Carvalho Chehab <mchehab@redhat.com>

commit e3c92215198cb6aa00ad38db2780faa6b72e0a3f upstream.

gcc 4.5+ doesn't properly evaluate some inlined expressions.
A previous patch were proposed by Andrew Morton using noinline.
However, the entire inlined function is bogus, so let's just
remove it and be happy.

Reported-by: Andrew Morton <akpm@linux-foundation.org>
Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
