[PATCH v3 3/3] i2c: i2c-qcom-geni: Update compile dependenices for I2C GENI driver
Posted by Jyothi Kumar Seerapu 2 days, 7 hours ago
I2C functionality has dependencies on the GPI driver.
Ensure that the GPI driver is enabled when using the I2C
driver functionality.
Therefore, update the I2C GENI driver to depend on the GPI driver.

So... without this change the previous patch is broken, which is a
no-go. And anyway, adding dependency onto a particular DMA driver is a
bad idea. Please make use of the DMA API instead.
