Subject[PATCH 6/9] Input: synaptics-rmi4 - make rmi_f34v7_erase_all() use the "erase all" command
Date
A full erase is required to recover from error conditions like "Bad
Partition Table". Various individual partition erase commands can be
(and need to be) omitted, as they will fail until a new partition table
has been written.
