mfd: ezx-pcap: Replace mutex_lock with spin_lock As mutex_lock might sleep. Function pcap_adc_irq is an interrupt handler. The use of mutex_lock in pcap_adc_irq may cause sleep in IRQ context. Replace mutex_lock with spin_lock to avoid this. Signed-off-by: Fuqian Huang <huangfq.daxian@gmail.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>
