genirq: Use pm_runtime_resume_and_get() instead of pm_runtime_get_sync()
pm_runtime_resume_and_get() achieves the same and simplifies the code. [ tglx: Simplify it further by presetting retval ] Reported-by: Zeal Robot <zealci@zte.com.cn> Signed-off-by: Minghao Chi <chi.minghao@zte.com.cn> Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Link: https://lore.kernel.org/r/20220418110716.2559453-1-chi.minghao@zte.com.cn
