Subject: [PATCH] extcon: extcon-max8997: Fix IRQ freeing at error path
Git-commit: 610bdc04830a864115e6928fc944f1171dfff6f3
Patch-mainline: v5.14-rc1
References: git-fixes
If reading MAX8997_MUIC_REG_STATUS1 fails at probe the driver exits
without freeing the requested IRQs.
Free the IRQs prior returning if reading the status fails.
Fixes: 3e34c8198960 ("extcon: max8997: Avoid forcing UART path on drive probe")
