What about following API?

bool dell_switchable_gfx_is_enabled(void);

Are you really interested in errors? Then what about?

Not really. We can assume it's false when there's any error.

I'll update the function in next version, thanks!

int dell_switchable_gfx_is_enabled(void);

with e.g.
  < 0 - error
  = 0 - disabled
0 - enabled
