mtd: mpc5121_nfc: drop devm_free_irq of devm_ allocated irq
The devm_request_irq function allocates irq that is released when a driver detaches. Thus, there is no reason to explicitly call devm_free_irq in probe or remove functions. Signed-off-by: Wei Yongjun <yongjun_wei@trendmicro.com.cn> Signed-off-by: Brian Norris <computersforpeace@gmail.com>
