A question of simplification

In Mathematica, when using partial differentiation, we get
D[c.f[x]]=0.f[x]+c.f'[x], not c.f'[x]. So, when the equation is long,
the result will be very tedious.
How can I simply the result to c.f'[x]? I have tested Simplify and
FullSimplify. It does not work.
Please help me! Thanks!
