The code that uses this function does an igt_require() on the its
return, so it will now pass even if value < 0. value was not modified
before for non existing params but it is now negative with your change.

The return is converted to bool, so even if value is negative it'll
become true. return value > 0?

you're breaking the assumption that val is not modified by the getparam

Same issues as the other is_coherent() function. BTW, maybe it'd be
worth moving it to a common place.

A lot of the params are booleans (i.e. the feature is either there or
not, no version), so we can maybe have a second level wrapper. something
like:
bool i915_has_feature(int fd, uint32_t param)
{
return drm_get_param(fd, param) > 0;
}
