If drv->probe is NULL, and dev_pm_domain_attach() fails, platform_drv_probe() will return the error code from dev_pm_domain_attach(). This causes real_probe() to enter the "probe_failed" path and set dev->driver to NULL. Before b8b2c7d845d5, real_probe() would assume success if both dev->bus->probe and drv->probe were missing. As a result, a device and driver could be "bound" together just by matching their names; this doesn't work any more after b8b2c7d845d5. This change broke the assumptions of certain drivers; for example, the TPM code has long assumed that platform driver and device with matching name could be bound in this way. That assumption may cause such drivers to fail with Oops during initialization after applying this change. Failure in suspend/resume tests under qemu has also been reported. This patch restores the previous (4.3.0 and earlier) behavior of platform_drv_probe() in the case when the associated platform driver has no "probe" function.
