Go to dashboardIn the Linux kernel's host1x bus code, the error teardown paths dereference client->ops without checking it for NULL, unlike the forward init paths. A NULL client->ops during a failed device init can crash the kernel.

host1x: bus: Fix missing ops null check in error teardown
In host1x_device_init(), the error teardown paths do not check client->ops before dereferencing it, unlike the forward init paths which correctly guard with 'client->ops &&'. This can result in a NULL pointer dereference if client->ops is NULL.
Fix by adding the missing client->ops check in both the teardown and teardown_late labels.
