2022-08-16i2c: Make remove callback return voidUwe Kleine-König1-3/+1
The value returned by an i2c driver's remove function is mostly ignored. (Only an error message is printed if the value is non-zero that the error is ignored.) So change the prototype of the remove function to return no value. This way driver authors are not tempted to assume that passing an error to the upper layer is a good idea. All drivers are adapted accordingly. There is no intended change of behaviour, all callbacks were prepared to return 0 before.

2017-06-06ASoC: cs35l35: Add additional delay for resetCharles Keepax1-1/+9
Very fast systems may violate the minimum constraints for time the reset line needs to remain low, or communicate with the device too soon after releasing the reset. Fix this by adding some delays in to allow the chip to properly reset, also factor out the reset into a function as it is likely it will be re-used in later additions to the driver.

2017-03-17ASoC: cs35l35: Stash dev pointer directly rather than CODEC pointerCharles Keepax1-15/+14
The driver stashes a CODEC pointer in the cs35l35_private structure, which is used to obtain a struct device pointer for error messages in the interrupt handler. However, doing so is not very safe as the interrupt is registered, as it should be in bus probe, but the CODEC pointer can't be safely stored until the ASoC level probe. This leaves a window between the two probes where if any interrupts are received a NULL pointer will be deferenced in the IRQ handler. Fix this issue by saving a pointer to the device directly and passing that to the error messages in the interrupt handler rather than using the CODEC pointer to access the device pointer.
