Subject: soundwire: cadence: Remove ret variable from sdw_cdns_irq()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=00d3c2b3f0a2cb26ef27f015015b43c8a195c10f;p=linux.git

soundwire: cadence: Remove ret variable from sdw_cdns_irq()

The ret is not used in the interrupt handler, it is just returned without
any condition or change.
We can return the IRQ_HANDLED directly.
