Tegra I2C Controller: Addresses a potential double-locking issue
 during probe. ACPI devices are not IRQ-safe when invoking runtime
 suspend and resume functions, so the irq_safe flag should not be
 set.
 
 Qualcomm GENI I2C Controller: Fixes an oversight in the exit path
 of the runtime_resume() function, which was missed in the
 previous release.
