2023-06-12mmc: dw_mmc: Make dw_mci_pltfm_remove() return voidUwe Kleine-König1-1/+1
dw_mci_pltfm_remove() returned zero unconditionally. Make it return void instead which makes its semantics a bit clearer. Convert the drivers that use this function as .remove() callback to .remove_new() which has the right prototype. This helps getting rid of the platform_driver's remove callback that returns an int (which is error prone). The other users didn't check the return value anyhow.

This is like commit 3d3451124f3d ("mmc: sdhci-msm: Prefer asynchronous probe") but applied to a whole pile of drivers. This batch converts the drivers that appeared to be around in the v4.4 timeframe.

Patch all drivers which use mmc_regulator_set_vqmmc() and prepare them for the fact that mmc_regulator_set_vqmmc() can return a value > 0, which would happen if the signal voltage switch did NOT happen, because the voltage was already set correctly.
