    media: i2c: et8ek8: Don't strip remove function when driver is builtin
    
    [ Upstream commit 545b215736c5c4b354e182d99c578a472ac9bfce ]
    
    Using __exit for the remove function results in the remove callback
    being discarded with CONFIG_VIDEO_ET8EK8=y. When such a device gets
    unbound (e.g. using sysfs or hotplug), the driver is just removed
    without the cleanup being performed. This results in resource leaks. Fix
    it by compiling in the remove callback unconditionally.
    
    This also fixes a W=1 modpost warning:
    
            WARNING: modpost: drivers/media/i2c/et8ek8/et8ek8: section mismatch in reference: et8ek8_i2c_driver+0x10 (section: .data) -> et8ek8_remove (section: .exit.text)
