[PATCH 5.5 047/120] rtc: mt6397: drop free_irq of devm_ allocated irq

[Greg Kroah-Hartman]

From: Wei Yongjun <weiyongjun1@xxxxxxxxxx>

commit 751438bc0f10f75633144acd6ff145f7260706d5 upstream.

The devm_request_threaded_irq function allocates irq that is
released when a driver detaches. Thus, there is no reason to
explicitly call free_irq in probe function.
