[PATCH RESEND v2 4/5] extcon: extcon-max8997: Fix IRQ freeing at error path

[Matti Vaittinen <matti.vaittinen@fi.rohmeurope.com>]

[-- Attachment #1: Type: text/plain, Size: 1423 bytes --]

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")
