[PATCH] rtc: mxc: use spin_lock_irqsave instead of spin_lock_irq in IRQ context

2019-08-07 Thread Fuqian Huang
As spin_unlock_irq will enable interrupts. mxc_rtc_irq_enable is called from interrupt handler mxc_rtc_interrupt. Interrupts are enabled in interrupt handler. Use spin_lock_irqsave/spin_unlock_irqrestore instead of spin_(un)lock_irq in IRQ context to avoid this. Signed-off-by: Fuqian Huang --- d
