[PATCH 1/3] i2c: stm32: fix the device used for the DMA map
From: Clément Le Goffic <hidden>
Date: 2025-06-16 08:57:56
Also in:
dri-devel, linux-i2c, linux-media, lkml
Subsystem:
i2c subsystem, i2c subsystem host drivers, st stm32 i2c/smbus driver, the rest · Maintainers:
Andi Shyti, Pierre-Yves MORDRET, Alain Volmat, Linus Torvalds
If the DMA mapping failed, it produced an error log with the wrong
device name:
"stm32-dma3 40400000.dma-controller: rejecting DMA map of vmalloc memory"
Fix this issue by replacing the dev with the I2C dev.
Fixes: bb8822cbbc53 ("i2c: i2c-stm32: Add generic DMA API")
