If desalinating ocean water becomes a widespread thing, is there potential for the ocean to become too salty/not salty enough as a result?

Suppose that desalinating ocean water becomes cheap and easy and it's used to solve the drinking water issue on earth.

If it's done too much could it have a negative impact on the ocean where the ocean becomes too salty or not salty enough? (Side q. Where does the salt in the ocean come from?)

Nope.  You drink.  You pee.  Water evaporates and it rains.  Most of that rain ends up in the ocean.  Water from the land drains to the oceans - I.e. the water cycle.  Fun fact the water molecules you drink today are the same ones a dinosaur drank 65 million years ago.  Water doesn't leave the planet.  

Ocean water is salty because salts existed on the Earth before water did.  Most of the water on Earth arrived from comets.  The oceans are the geologically lowest areas on the planet.  The salts and minerals that exist on Earth dissolved in the oceanic basins that formed over time.  Once clouds and rain existed, the rivers and glaciers that formed washed more salts into the oceans.
