The remove callback is only called after probe completed successfully. In this case platform_set_drvdata() was called with a non-NULL argument and so !sdev is never true. The motivation for this change is to get rid of non-zero return values for remove callbacks as their only effect is to trigger a runtime warning. See commit e5e1c2097881 ("driver core: platform: Emit a warning if a remove callback returned non-zero") for further details.
