Subject[PATCH] ASoC: es8316: Handle optional IRQ assignment
Date
The driver is able to work fine without relying on a mandatory interrupt
being assigned to the I2C device. This is only needed when making use of
the jack-detect support.

However, the following warning message is always emitted when there is
no such interrupt available:

es8316 0-0011: Failed to get IRQ 0: -22

Do not attempt to request an IRQ if it is not available/valid. This also
ensures the rather misleading message is not displayed anymore.

Also note the IRQ validation relies on commit dab472eb931bc291 ("i2c /
ACPI: Use 0 to indicate that device does not have interrupt assigned").

Fixes: 822257661031 ("ASoC: es8316: Add jack-detect support")
