Zhou Qingyang 9b6d90e208 ata: pata_platform: Fix a NULL pointer dereference in __pata_platform_probe() ... In __pata_platform_probe(), devm_kzalloc() is assigned to ap->ops and there is a dereference of it right after that, which could introduce a NULL pointer dereference bug. Fix this by adding a NULL check of ap->ops. This bug was found by a static analyzer. Builds with 'make allyesconfig' show no new warnings, and our static analyzer no longer warns about this code.
