-Subject: [PATCH 113/113] mtd: spi-nor: fsl-quad: move mtd_device_register to
- the last of probe
-
-After call mtd_device_register, the mtd devices should be workable immediately.
-If before finish all of init work call the mtd_device_register, it will not
-respond work request timely.
-
-For example, openwrt/lede have a AUTO split special flash partitions mechanism
-while mtd driver register. So, before call mtd_device_register, must let all of
-init work ready.
