Subject: [PATCH] dmaengine: pxa_dma: use platform_get_irq_optional
Git-commit: b3d726cb8497c6b12106fd617d46eef11763ea86
Patch-mainline: v6.1-rc5
References: git-fixes

The first IRQ is required, but IRQs 1 through (nb_phy_chans - 1) are
optional, because on some platforms (e.g. PXA168) there is a single IRQ
shared between all channels.

This change inhibits a flood of "IRQ index # not found" messages at
startup. Tested on a PXA168-based device.
