Subject: [PATCH] tps65090-charger: drop devm_free_irq of devm_ allocated irq

From: Wei Yongjun <yongjun_wei@...ndmicro.com.cn>

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.
