So stop treating the failure to add a single cell as an error. Those messages can be printed at notice level. And then only warn if no cells were added. Signed-off-by: Paul Bolle --- 0) This patch was written on top of v3.7-rc4 and tested on v3.6.7. 1) Please note that this patch prints a warning when no MFD cells are added at all. I didn't make that an error because I'm not sure there's anything one can do if this happens.
