[PATCH] input: misc: drv260x: add check for ERM mode and LRA Libraries

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Add a check to ensure that LRA libraries are not mixed with
the ERM mode.

If ERM mode and the Library is empty "OR" the
LRA library then exit.

As the LRA and empty libraries are not applicable for
the ERM actuator.
