question about v4l2_i2c_new_subdev_board

Hello, Hans, Mauro

I find in source code: v4l2-common.c: v4l2_i2c_new_subdev_board(),
there is a comment:

/* Note: by loading the module first we are certain that c-
>driver
ÂÂÂwill be set if the driver was found. If the module was not
loaded
ÂÂÂfirst, then the i2c core tries to delay-load the module for
us,
ÂÂÂand then c->driver is still NULL until the module is finally
ÂÂÂloaded. This delay-load mechanism doesn't work if other
drivers
ÂÂÂwant to use the i2c device, so explicitly loading the module
ÂÂÂis the best alternative. */

I find it added by commit: f0222c7d860f09a61bec5e500539f28db0184b38

it was added at year 2009, is this still an issue in newer kernel, like
4.14?

BR.
Ning.
