iio: adc: stm32-adc: fix device used to request dma
[ Upstream commit 52cd91c27f3908b88e8b25aed4a4d20660abcc45 ]
DMA channel request should use device struct from platform device struct.
Currently it's using iio device struct. But at this stage when probing,
device struct isn't yet registered (e.g. device_register is done in
iio_device_register). Since commit 71723a96b8b1 ("dmaengine: Create
symlinks between DMA channels and slaves"), a warning message is printed
as the links in sysfs can't be created, due to device isn't yet registered:
- Cannot create DMA slave symlink
- Cannot create DMA dma:rx symlink
Fix this by using device struct from platform device to request dma chan.
Fixes: 2763ea0585c99 ("iio: adc: stm32: add optional dma support")
